Mother’s Day Extra Questions and Answers Long Answer Type

Question 1.
Write in your words the conversation between Mrs Pearson and Mrs Fitzgerald in the beginning of the play. What is the outcome of the meeting?
Answer:
Mrs Fitzgerald predicts her friend Mrs Pearson’s fate and tells her that it was high time she asserted herself as the head of the family. Mrs Pearson says that it was not easy because she loves her family although they are very thoughtless and selfish. But Mrs Fitzgerald insists that they ought to learn to appreciate her and treat her appropriately. She tells her not to run after them and oblige. Mrs Pearson agrees with Mrs Fitzgerald, but wonders if anything would affect them.

She is afraid of creating unpleasantness in the family. As Mrs Pearson is about to rush off to prepare dinner for her family, Mrs Fitzgerald comes up with an idea. She tells . Mrs Pearson that they could exchange their bodies. She then holds her hand and asks her to keep quiet for a minute. They stare at each other and Mrs Fitzgerald mumbles ‘Arshtatta dum—arshtatta lam—arshtatta lamdumbona…’ and they assume each other’s personality.

Question 2.
What does Mrs Pearson have to say to Doris that disturbs her?
Answer:
When Mrs Pearson’s daughter Doris returns and tells Mrs Fitzgerald, in the body of Mrs Pearson, to iron her yellow silk dress as she would like to wear it that night, her mother continues playing patience. Doris asks her what she is doing and she answers her smugly that she was not whitewashing the ceiling. She also says that there is no law against smoking. She informs Doris that she had already had her tea but had not made tea for the others.

She had not cooked dinner either and would have her meal at the Clarendon. She tells Doris that she worked twice as hard as the others and got no wages or thanks for it. She then inquired from Doris where she wanted to wear her yellow dress. Doris tells her that she was going out with Charlie Spence. Mrs Pearson tells her to find someone better than the buck-toothed and half-witted man. Doris is offended and runs out.

Question 3.
Describe Mrs Pearson’s conversation with Cyril when he walks in and his reaction.
Answer:
Mrs Pearson’s son Cyril walks in and insists on Mrs Pearson getting the tea and his clothes ready. He reminds her of the promise she made the same morning, to mend his clothes. He is surprised to hear that she does not Tike mending’ and that she would not do anything that she did not want to do. Cyril could not believe his ears. Cyril again asks for tea, telling her that he had been working for an eight-hour day, to which Mrs Pearson says that she had done her eight hours and henceforth she would work for only forty hours a week. On weekends, she would have her two days off.

She might make a bed or two and do a bit of cooking as a favour but that would be conditional to the fact that they asked her very nicely and thanked her for everything and generally made a fuss of her. Cyril and Doris are surprised and wait for their father to arrive.

Question 4.
“Sometimes it does people good to have their feelings hurt.” Who says this and what does she say to hurt Mr Pearson?
Answer:
When Mr Pearson announces that he did not wish to drink tea, after he returned from work, the real Mrs Fitzgerald informs him that his tea was not ready. He is angry and she reminds him that he was annoyed because he did not get the tea that he did not want in the first place. She adds that if he did that at bar—went up to the bar at the club and told them he did not want a glass of beer but got irritated because they had not already poured it out for him, they would laugh at him even more than they did already.

George was indignant and she added that he was one of their standing jokes and was called ‘Pompy-ompy Pearson’ because they thought that he was slow and pompous.
George checks with Cyril on the truth of the matter, and Cyril accuses his mother of not being fair and sensitive. To which, she replies that sometimes it does people good to have their feelings hurt.

Question 5.
Pick out the instances that bring out the element of humour in the play.
Answer:
The play is a light-hearted comedy. A mother accomplishes changing the attitude of her family by exchanging her body with her friend, Mrs Fitzgerald, a bold and assertive woman, thus, introducing humour in the play. The moment the spirits change, Mrs Pearson notices the cigarette, snatches it off Mrs Fitzgerald, while she looks down at her changed body and screams out of fright.

Mrs Pearson answers to her daughter’s query, sarcastically, that she was not whitewashing the ceiling. Mrs Pearson insults Doris’ date, comically, calling him ‘buck-toothed and half-witted’. Cyril is told that she does not ‘like mending’ his clothes, stunning him to silence. When Mrs Pearson walks out, Doris and Cyril laugh at the idea of her having gone crazy and decide to wait till the father comes. She tells Mr Pearson how he was a standing joke in the club and was called ‘Pompy-ompy Pearson’ because they thought that he was slow and pompous. She also tells him that he was George, and not the Duke of Edinburgh.

Question 6.
Mrs Fitzgerald’s effort does not go in vain, as the family changes for the better. Justify.
Answer:
Mrs Pearson has a selfish and a thoughtless family, who is insensitive to the feelings of the mother. But after the staged trick, and when Mrs Fitzgerald leaves, the three—George, Doris, and Cyril look anxiously at Mrs Pearson, who smiles. They are much relieved, and smile back at her. Mrs Pearson tells them that since they have decided to stay at home, they would have a nice family game of rummy and then the children could get the supper ready while she talked with their father. All of them agree. Mrs Pearson wishes Mrs Fitzgerald goodbye and the family surrounds Mrs Pearson, implying a happy ending. It looks as if Mrs Fitzgerald’s effort is rewarded and they seem eager to appease the real Mrs Pearson.

Silk Road Extra Questions and Answers Short Answer Type

Silk Road Class 11 Extra Questions And Answers Question 1.
when they set out on their journey.
Answer:
The narrator was moving towards Mount Kailash to complete the kora. He recalls the day, when they set out from Ravu, with nostalgia. It was a ‘perfect’ early morning to start a journey. The clouds looked like long French loaves glimmering pink as the rising sun shone on them. The far-away mountain peaks glowed with a rose-tinted colour. Lhamo presented him with one of the long-sleeved sheepskin coats that all the men there wore, for protection against cold.

Silk Road Extra Questions And Answers Question 2.
Describe the initial phase of their journey.
Answer:
As they set out, they took a shorter route to get off the Changtang. It was a road that would take them south¬west, almost directly towards Mount Kailash. It required crossing several quite high mountain passes. Tsetan was confident that if there was no snow they would have a comfortable journey but that they would not know till they got there.

From the gently sloping hills of Ravu, the short cut took them across vast open plains with nothing in them except a few antelopes grazing in the arid pastures. As they moved ahead, the plains became more stony than grassy. There, the antelopes were replaced by herds of wild ass.

Silk Road Class 11 Questions And Answers Question 3.
What did the narrator notice about the ‘drokbas’?
Answer:
As the narrator went further up the hills from the rocky wasteland, he noticed the solitary drokbas tending their flocks. Sometimes these well-wrapped figures would halt briefly and stare at their car. They seldom waved as they crossed. When the road took them close to the sheep, the animals would swerve away from the speeding car.

Extra Questions Of Silk Road Class 11 Question 4.
The narrator was fascinated by the awesome mastiffs. Why?
Answer:
Crossing the nomads’ dark tents pitched in remoteness, the narrator noticed that a huge black dog, a Tibetan mastiffs, guarded most of the tents. These monstrous creatures would tilt their great big heads when someone moved towards them. As they drew closer, these dogs would race straight towards them, like a bullet from a gun. These dogs were pitch black and usually wore bright red collars.

They barked furiously with their gigantic jaws and were so fearless that they ran straight into the path of their vehicle. They would chase them for about a hundred metres. The narrator could understand why Tibetan mastiffs became popular in China’s imperial courts as hunting dogs.

Silk Road Extra Questions Class 11 Question 5.
How did Tsetan manoeuvre across the first patch of snow that they came across?
Answer:
Tsetan stopped at a tight bend and got out because the snow had covered the path in front of them. This unexpected-depository was too steep for their vehicle to mount. Tsetan stepped on to the covered snow, and stamped his foot to determine how sturdy it was. The snow was not deep but the car could turn over. Tsetan took handfuls of dirt and threw them across the frozen surface. Daniel and the narrator, too, joined in. When the snow was spread with soil, Tsetan backed up the vehicle and drove towards the dirty snow. The car moved across the icy surface without noticeable difficulty.

Silk Road Questions And Answers Class 11 Question 6.
When did the narrator feel unwell or the first time? What did he do?
Answer:
When they went further up the trail and were 5,400 metres above the sea level, the narrator got an awful headache. He took gulps from his water bottle, which is supposed to help during a speedy uphill journey. His headache soon cleared as they went down the other side of the pass.

Class 11 Silk Road Extra Questions Class 11 Question 7.
What was the sight on the plateau ruins of the Tethys Ocean?
Answer:
The narrator and his friends stopped for lunch in a long canvas tent, part of a work camp erected beside a dry salt lake. The plateau was covered with salty desert area and salty lakes that were remnants of the Tethys Ocean. This place was bustling with activity. Men with pickaxes and shovels were moving back and forth in their long sheepskin coats and salt-covered boots. All wore sunglasses as protection against the dazzling light of blue trucks that energed from the lake with piles of salt.

Silk Road Question Answer Class 11 Question 8.
Why was the narrator sorry to see the miserable plight of Hor?
Answer:
Hor was a dismal place with no vegetation. It only had dust and rocks coupled with years of accumulated refuse. He found this unfortunate because this town was on the banks of Lake Manasarovar, Tibet’s most venerated stretch of water.

Class 11 English Silk Road Extra Questions Question 9.
What is the belief about Lake Manasarovar? What is the fact?
Answer:
According to ancient Hindu and Buddhist cosmology Manasarovar is the source of four great Indian rivers: the Indus, the Ganges, the Sutlej and the Brahmaputra. In actuality only the Sutlej flows from the lake, but the headwaters of the all others rise nearby on the flanks of Mount Kailash.

Important Questions Of Silk Road Class 11 Question 10.
The narrator ‘slept very soundly. Like a log, not a dead man’. Explain.
Answer:
After going to the Tibetan doctor the narrator soon recovered. Unpalatable as it seemed, the medicine led him to a quick recovery. Hence the narrator had a healthy and sound sleep unlike when he was ailing and restless. He slept undisturbed. He was not tossing and turning because he was sound a sleep, not because he felt lifeless.

Silk Road Important Questions Class 11 Question 11.
‘Darchen didn’t look so horrible after a good night’s sleep.’ Justify
Answer:
The narrator had a very uncomfortable night at Darchen. After he rested, although Darchen was dusty, with heaps of rubble and refuse, the bright sun in a clear blue sky gave the narrator a view of the Himalayas. He also noticed the huge, snow-capped mountain, Gurla Mandhata, with just a tuft of cloud suspended over its peak.

Question 12.
‘I hadn’t made much progress with my self-help programme on positive thinking.’ Why does the narrator feel so?
Answer:
The narrator was very disappointed with Darchen. It was dusty, with heaps of rubble and refuse. But he was even more disappointed as there were no pilgrims. As his mind went over the drawbacks of the place he concluded that he hadn’t made much progress with his self-help programme on positive thinking. In that case he would have been more accepting and optimistic.

Question 13.
Who was Norbu? How could he be a help to the narrator?
Answer:
The narrator met Norbu in a cafe. He was Tibetan, and worked in Beijing at the Chinese Academy of Social Sciences, in the Institute of Ethnic Literature. He had come to do the kora. Norbu had been writing academic papers about the Kailash kora and its importance in various works of Buddhist literature for many years but .he had never actually done it himself. The narrator was relieved to team up with him. He would not be alone then.

Question 14.
‘He suggested we hire some yaks to carry our luggage, which I interpreted as a good sign’. Why does the narrator feel so?
Answer:
The narrator was relieved at meeting Norbu. He kept telling the narrator how fat he was and how hard it was going to be for him to climb. He wasn’t really a practising Buddhist, but he was enthusiastic and was a Tibetan. Making the trek in the company of devout believers would not be easy as they would go prostrating all round the mountain. But Norbu suggested that they hire some yaks to carry our luggage. This to the narrator came as a relief.

Silk Road Extra Questions and Answers Long Answer Type

Question 1.
The narrator on his way to Mount Kailash came across a lot of topographic variation. Comment.
Answer:
The narrator and his companions took a short cut to get off the Changtang. Tsetan knew a route that would take them southwest, almost directly towards Mount Kailash. It involved crossing several fairly high mountain passes. From the gently rising and failing hills of Ravu, the short cut took them across vast open plains with nothing in them except a few gazelles that were grazing in the arid pastures. Further ahead,
the plains became more stony than grassy, and there a great herd of wild ass came into view.

Still ahead hills became steeper wh^re solitary drokbas were tending their flocks. This led them to the snow-capped mountains and then to the valley where the river was wide and by and large clogged with ice. At a height of 5,515 metres, piles of stones marked the landscape. Next was the plateau which was covered with salty desert area and salty lakes that were remnants of the Tethys Ocean. Hor was next in line. It was a wretched place with no vegetation just dust and rocks, liberally scattered with years of accumulated refuse.

Question 2.
The narrator realized that the snow was both dangerous as well as beautiful. Justify.
Answer:
Tsetan on his way surveyed the snow on the path by stamping on it. It was not deep. But in case they slipped the car could turn over. Hence to cover the risk, they flung handfuls of dirt across the frozen surface. When the snow was spread with soil, they drove without difficulty. Ten minutes later, they stopped at another blockage. This time they decided to drive round the snow.

However, the risks did not undermine the scenic beauty of the place. In the valley, they saw snow-capped mountains and the river was wide but mostly blocked with ice that was sparkling in the sunshine. As they moved ahead, on their upward track, the turns became sharper and the ride bumpier. The rocks around were covered with patches of bright orange lichen. Under the rocks, seemed unending shade.

Question 3.
Enumerate the difficulties that the group faced in Hor.
Answer:
The group reached the small town of Hor by late afternoon. Daniel, who was returning to Lhasa, found a ride in a truck and left. They had suffered two punctures in quick succession on the drive down from the salt lake and they got them replaced. Hor was a gloomy place devoid of vegetation. It only had dust and rocks, liberally scattered with years of accumulated refuse.

Hor’s only cafe which, like all the other buildings in town, was constructed from badly painted concrete and had three broken windows. The good view of the lake through one of them helped to compensate for the draught. The narrator was served by a Chinese youth in military uniform who spread the grease around on his table with a filthy rag before bringing him a glass and a thermos of tea.

Question 4.
Describe in detail the narrator’s miserable night in Darchen.
Answer:
The narrator reached the Darchen guesthouse after 10.30 p.m. This was just the beginning of a troubled night. The open-air rubbish dump in Hor had set off his cold once more. One of his nostrils was blocked again and he was tired and hungry. He started breathing through his mouth. After a while, he woke up abruptly. His chest felt strangely heavy but when he sat up, his nasal passages cleared almost instantly and relieved the feeling in his chest. He lay down again. Just as he was about to doze something told him not to.

He was not gasping for breath, but could not go to sleep. He sat up but as soon as he lay down, his sinuses filled and his chest felt strange. He tried supporting himself against the wall, but could not manage to relax enough to sleep. He did not know what was wrong but had a feeling that if he slept he would not wake up again. So he stayed awake all night.

Question 5.
Narrate the narrator’s meeting with the Tibetan doctor.
Answer:
After an awfully uncomfortable and breathless night, Tsetan took the narrator to the Darchen Medical College. The college was new and looked like a monastery from the outside with a very solid door that led into a large courtyard. The consulting room was dark and cold and occupied by a Tibetan doctor who did not have any kit that the narrator had been expecting.

He wore a thick pullover and a woolly hat. The narrator explained the symptoms and the doctor shot him a few questions while feeling the veins in his wrist. Finally he said, it was the cold and the effects of altitude. He said that the narrator would be well enough to do the kora. He gave him a brown envelope stuffed with fifteen screws of paper. Each package had a brown powder that had to taken with hot water. It tasted just like cinnamon. The contents of the lunchtime and bedtime packages were less obviously identifiable. Both contained small, spherical brown pellets. Though the medicine looked like sheep dung, it helped him recover quickly.

Question 6.
Meeting Norbu came as an immense relief to the narrator. Why?
Answer:
The narrator was not only disappointed with the filth in Darchen but also because of the lack of pilgrims. Moreover, since Tsetan had left, he had not come across anyone in Darchen with enough English to answer even this most basic question. It was then that he met Norbu in a cafe. He was Tibetan, he told him, but worked in Beijing at the Chinese Academy of Social Sciences, in the Institute of Ethnic Literature.

He had also come to do the kora. Norbu had been writing academic papers about the Kailash kora and its importance in various works of Buddhist literature for many years, but he had never actually done it himself. He was relieved to form a team with another academician. This apart, Norbu, wasn’t really a practising Buddhist, though he was a Tibetan. He suggested that they hire some yaks to carry their luggage, as he had no intention of prostrating himself all round the mountain.

His thoughts turned to Denny, living unhappily, away from his wife. His reason told him that all these marriages were dismal failures. It was a conclusion, which made him cringe in his present state. He wished to consider marriage as a peaceful state. The conflict between his cynical mind and his ’ heart, eager to love, left him bitter and confused.

Class 11 English Chapter Birth Extra Questions Question 3.
Andrew’s visit to the Morgan’s gave him pleasure and satisfaction that he had not achieved earlier. Justify.
Answer:

He injected the medicine and struggled to restore the lifeless Susan Morgan, and after a few minutes of intense effort, her heartbeat became steady.

Andrew then turned his attention to the lifeless baby. He inferred the condition was caused by lack of oxygen in the baby’s blood. He initiated the artificially induced method of respiration. Pouring cold water into one basin and warm, into the other, he rushed the child, from one basin to the next, for fifteen minutes.

As his last resort, he rubbed the child with a rough towel, crushing and releasing the little chest with both his hands, trying to get breath into that limp body.Then miraculously, the tiny chest began heaving and they heard the child’s cry. He had saved two lives and was eternally relieved at having ‘done something real at last.’

The poet has discussed two stages of life – childhood and adulthood. How do we differentiate one from another?
Answer:
Childhood has been considered by the poet as a blissful period in one’s life, where a child trusts everyone.
Adulthood is marked by rational and creative thoughts, ability to perceive and differentiate and learn new things. In this stage of life one also learns to be double faced and crafty.

Childhood Extra Questions Question 3.
What did the poet realise when he crossed the age of eleven years?
Answer:
When the poet crossed the age of eleven years, he realised that he had lost his childhood and had developed a mind of his own. He also found out the non-existence of Hell and Heaven.

Childhood Class 11 Extra Questions Question 4.
How did the poet conclude that Hell and Heaven were imaginary places?
Answer:
The poet concluded that Hell and Heaven were imaginary places because Geography books contain names of places, but there is no mention of places like Hell or Heaven in these books.

Class 11 English Childhood Extract Questions Question 5.
How did adults seem to the poet when he was a child?
Answer:
As a child, the poet considered all the adults as an epitome of love and sincerity. He believed that their love was true and they were ready to do anything for , their loved ones.

Childhood Question Answer Question 6.
Bring out the hypocrisy that the adults exhibit with regard to love.
Answer:

Class 11 Childhood Extra Questions Question 8.
What is the poet trying to convey when he says that childhood is hidden in an infant’s face?
Answer:
The poet says an infant is really innocent as he trusts everyone and does not try to fool others. The poet brings out this fact by contrasting it with the behaviour of adults, who become manipulative and are hypocrites. As a person develops rational thoughts, his childlike innocence fades away.

Childhood Class 11 Ques Ans Question 9.
According to Markus Natten, when does the child become an adult?
Answer:
Becoming an adult is a complex process which is associated with physical, mental and social development.

He also develops his own thought process, using which he can form his own beliefs and opinions.

Childhood Important Questions Question 10.
What is the poet’s feeling towards his childhood?
Answer:
The poet regards childhood as a period of innocence. A child sincerely feels that he is free from all evils and that there is really a Hell and a Heaven. A child knows no hypocrisy. There is no difference between his thoughts and actions. In short, childhood is a state of innocence and purity of heart.

Childhood Class 11 Questions And Answers Pdf Question 11.
How does the poem expose man and present him in true colours?
Answer:
According to the poet, childhood symbolises innocence, purity, softness and love. As a child grows up, these qualities start receding. Man adheres to lying, shrewdness, cunningness and hypocrisy.

Adults preach about truth and honesty but themselves practise hatred and lying. The simplicity and honesty of childhood evaporates the moment man crosses the threshold of innocent childhood.

Childhood Extra Questions and Answers Long Answer Type

Childhood Extra Questions Class 11 Question 1.
Write an article in about 150 words about childhood and the process of growing up.
Answer:

Childhood
by Manav Singh

When I was a child the world seemed to be a place of joy and happiness to me. There was nothing worth worrying about. Whenever I cried, somebody consoled me. When I did not like to sit alone, I was always in somebody’s arms. My mother always looked after me. These are my most cherished memories and I believe that looking at a child playing and enjoying childhood makes me somewhat nostalgic.

Childhood is free from cares. There are no duties or responsibilities on the shoulders of a child. A child only eats, drinks, sleeps and plays. Thus, a child lives in the bliss of ignorance and innocence. As we grow in age, worries about studies, choice of profession, shouldering responsibilities etc keep haunting us. Tensions, stress and worries become a part of adult life and the individual forgets to live a carefree life.

Childhood Class 11 Important Question Question 2.
Is independent thinking a step towards adulthood? If yes, then how? Explain with reference to the poem ‘Childhood’.
or
Markus Natten, though showing disapproval regarding the behaviour of adults, also raises a very important point, that of independent thinking and individuality. Do you agree that independent thinking and individuality make us what we are? Elaborate in the context of the poem ‘Childhood’.
Answer:
Of course, independent thinking is a step towards adulthood. As a child, one is not able to make one’s own decisions and one’s thinking is always influenced and directed by adults. A child is so innocent that it is not able to distinguish between truth and imagination.

As a child’s thinking is influenced by others, it has no individuality. Moreover, it is prone to manipulations which lead to fickle-mindedness. Independent thinking makes us what we are. It shapes our personality and we are known among people through what our mind thinks and what decisions we take.

If we want to stay away from evil people who try to influence our thoughts for their selfish purposes, then only independent thinking can help us. We cannot claim to be an individual if we cannot take decisions ourselves.

The Voice of the Rain Extra Questions and Answers Short Answer Type

Voice Of The Rain Extract Questions Class 11 Question 1.
Why does the poet get surprised when he gets an answer from the rain?
Answer:
The poet gets surprised when he gets an answer from the rain, as it is inanimate and cannot speak. In this poem, to the poet’s and reader’s amazement, the rain gives a reply which has been translated by the poet for the readers.

The Voice Of The Rain Extra Questions Class 11 Question 2.
What answer does the rain give back to the poet?
Answer:
The rain answers to the poet’s question by telling him that it is the Poem of Earth and is involved in a continuing process of going up and coming down.

Voice Of The Rain Extra Questions Class 11 Question 3.
How does the rain justify its claim ‘I am the Poem of Earth’?
Answer:
The rain calls itself the Poem of the Earth because the poem rendered by the poet has the task of bringing joy, happiness, life to its readers. Similarly when the rain falls down over Earth, a rhythm or music is created. That’s why the rain calls itself the Poem of Earth.

Voice Of The Rain Extra Questions And Answers Class 11 Question 4.
Describe the never ending cycle of rain.
Answer:
Water rises unperceived in the form of vapour from land and water bodies on the Earth. It goes up, takes the form of a cloud, changes its shape and falls down on Earth in the form .of water drops to bathe the small dust particles, land and sea. The water returns through rivers to oceans and seas after it rains on Earth.

The Voice Of The Rain Extract Based Questions Class 11 Question 5.
Why does the rain call itself ‘impalpable’?
Answer:
Impalpable means something that cannot be felt by touching or seeing. When water takes the form of vapour, it is not visible to the human eye and nor can we feel its touch.

The vapour rises to the sky, condenses and forms clouds which cause rain. Though we are aware of its presence, the process remains invisible to us. Hence, the rain has rightly called itself ‘impalpable’.

The Voice Of The Rain Question Answer Class 11 Question 6.
What happens when it rains after a long hot spell?
Answer:
After a long hot spell, everything is dried up on Earth. When it rains, all the dust that has accumulated on Earth gets washed away, giving a new fresh look to nature. Moreover the seeds which were lying latent till now, get germinated with the help of rain and new trees and plants start growing.

The Voice Of The Rain Class 11 Extract Questions  Question 7.
Latent seeds get a life by rain. Explain.
Answer:
The seeds lying on Earth require water to germinate and take shape. When it rains, the seeds start germinating and change into the form of saplings. In this way, the seeds which would have dried up or get wasted get a new lease of life by rain.

The Voice Of The Rain Question And Answer Class 11 Question 8.
Why is rain essential for Earth?
Answer:
If it doesn’t rain then Earth will remain parched, droughts will follow and the dust-layers will not be washed away. There will be nothing to quench the thirst of the plants and trees and their seeds will die.

The Voice Of Rain Extra Questions Class 11 Question 9.
How does the rain become the voice of Earth?
Answer:
In the poem, ‘The Voice of the Rain’, the poet describes how the rain falls on Earth. He also asks a question to the rain’about it. He calls the showers of the rain as ‘Poem of Earth’ as the rain gives a new lease of life to ‘ the scorched and parched Earth and falls on Earth in a rhythmic manner.

Actually, it is the voice of Earth as the slowly falling showers produce a very soft music and Earth finds its expression only through the showers falling on it.

Voice Of The Rain Questions Class 11 Question 10.
Why do you think the poet says the phrase ‘reck’d or unreck’d’?
Answer:
The words have been poetically drafted. Reck’d and unreck’d stand for reckoned and unreckoned. The words literally mean cared and uncared for respectively. The poet says these words to emphasise the fact that when it falls on the Earth, we sometimes take notice of it or sometimes completely ignore it. But even if it is left uncared for, it completes its destiny and returns to absorbed where it started from.

Voice Of Rain Extra Questions Class 11 Question 11.
Justify the title ‘The Voice of the Rain’.
Answer:
The whole poem is about the eternal process of rain and its benefits. Through the words of the rain, the poet has tried to bring out the importance of rain for Earth, for plants and for man. As the poet is translating what the rain is speaking through its own language (the sounds it makes when it falls), the whole poem is about the rain talking to the poet. Thus, the title is justified.

The Voice Of The Rain Important Questions Class 11 Question 12.
The poem has a conversational tone throughout. Who are the two participants? Is there any advantage of this method?
Answer:

The poem ‘The Voice of the Rain’ gives a hidden message that rain is essential for this Earth. Write an article in 120-150 words describing the importance of rain.
Answer:

Importance of Rain
by Ali Jawed

As we all know, the three essentials for survival are water, food and air. The most important element of weather is water. We get water in different forms of precipitation but rain is the most beneficial of all types of precipitation.

Rain helps in harvesting our crops that give us food to eat. Without rain, no crops would grow and we would perish. Also, falling showers remove the dust in air, making our air clean, because we need clean air to breathe.

Rain water plays a key role in creating the climate of certain areas. Its presence in the atmosphere provides replenishment of the moisture in cloud systems.

The most well-known and most important effect of rain water is to provide us with water to drink. Without rain, there would be no life.

Extra Questions Of The Voice Of The Rain Class 11 Question 2.
Rain is an eternal process benefiting mankind. Contrast it with human life which is short lived on this Earth. Should we disturb these eternal elements of nature?
Answer:
The poem ‘The Voice of the Rain’ beautifully shows the continued process of rain which sounds like music to human ears, as it fulfills our needs.

It is an ever going process which sustains human life and provides us with food, pure air and green cover. On the other hand, human lives are mortal. We come on this Earth for a short period and then depart without leaving any mark on this planet. Moreover human beings, for their greed and selfish motives, indulge in destructive activities which may disturb these eternal processes of nature.

We must learn a lesson from nature. If we want peaceful co-existence, we need not disturb the balance of nature, otherwise the whole of humanity will be in danger. We must learn a lesson from such eternal processes and do something good for humanity at large.

Voice Of The Rain Important Questions Class 11 Question 3.
Natural elements such as air and rain make no discrimination and bless everyone equally. Comment on class distinction and inequality, which is a totally human creation.
Answer:
Man’s existence on this Earth is short-lived but even in this short span, he has been responsible for many wrong doings against other human beings. God has created everyone as equal. But it is very unfortunate that man has divided this society on the basis of class, caste and other factors.

Man must learn from elements of nature which provide us fresh air, heat or water, without making any distinction. But in human society class distinctions and caste distinctions both exist and inequalities prevail in large numbers. It is high time that man must learn lessons from nature and adopt universal brotherhood for the betterment of our society.

Question 12.
Read the passage given below and answer the questions that follow.
Decomposition of ammonia to hydrogen (and nitrogen) requires an energy input, and since the decomposition reaction is very slow even at relatively high temperatures, a catalyst is also needed. Since the reaction is an equilibrium reaction, it is not possible to completely decompose ammonia into hydrogen. Maximizing the efficiency of a complete fuel cell system utilizing metal amines for hydrogen storage,therefore, requires both efficient heat integration to minimize losses and a properly designed catalyst system to achieve a sufficiently fast hydrogen production rate.

For fuel cell systems that are not tolerant to ammonia, it is also necessary to include an ammonia scavenger. These units are already well known in the chemical industry. Historically, ammonia decomposition has received most of its attention as a model reaction studied to gain fundamental insight into the technically important ammonia synthesis reaction (Hansen, 1995).

However, a few industrial ammonia decomposition plants are currently in operation to produce deuterium-enriched ammonia by coupling consecutive synthesis- decomposition cycles combined with distillation. These plants operate at moderate pressures but at quite high temperatures (600 °C).

Section-A

Question 1.
Arrange the following in the increasing order of their property indicated (Any 2):
CBSE Sample Papers for Class 11 Chemistry Term 2 Set 2 with Solutions 1
(ii) n-butane, 2-methylbutane, n-pentane, 2,2-dimethylpropane (boiling points)
(iii) H2C=CH2, (CH3)2C = CH2 ,CH3– CH= CH2, CH3 -CH= CH -CH2 – CH3
(electrophilic addition reaction)
Answer:
(i) CH3Br does not have any β-carbon so it would not show any reaction. More the number of β-substituents
(alkyl groups), more stable alkene will be formed on β-elimination and more will be the reactivity. Thus, the increasing order of reactivity of the rate of β- elimination with aic. KOH is
CBSE Sample Papers for Class 11 Chemistry Term 2 Set 2 with Solutions 2
(ii) n-butane < 2,2-dimethyipropane < 2-methyl butane < n-pentane. As the number of carbon atoms in the chain increases, boiling point increases. Boiling point decreases with increase in branching.

(iii) The stability of the intermediate carbocation determines the reactivity towards electrophilic addition reactions. Due to the inductive effect (+1) of alkyl group, the bigger is the attached alkyl group, the more stable is the intermediate ion. Thus, the order of stability of carbocation is: Primary carbocation(1°) < Secondary carbo cation (2°) alkenes towards electrophilic addition reactions increases in the order:
H2C=CH2, <CH3-CH= CH2 <CH3-CH=CH-CH2-CH3 <(CH3)2C= CH2

Question 2.
Out of the two pairs of compounds given below, identify the compound in each of the pairs which has Group 13 element in more stable oxidation state. Mention the nature of bonding too.
(i) TlCl3,TlCl
(ii) AlCl3, AlCl
Answer:
(i) TlCl has more stable oxidation state than TlCl3 because on moving down the group due to inert pair effect, lower oxidation state is more stable. TlCl is ionic in nature.

(ii) AlCl3 has more stable oxidation state than AlCl because it does not display inert pair effect. The anhydrous state of AlCl3 is covalent while its aqueous state is ionic in nature.

Question 3.
Give reasons to support your answer:
(i) Benzene is extraordinarily stable though it contains three double bonds.
(ii) Toluene on Friedel-Crafts methylation gives o- and p-xylene.
Answer:
(i) Benzene is a hybrid of resonating structures given as:
CBSE Sample Papers for Class 11 Chemistry Term 2 Set 2 with Solutions 3
All six carbon atoms in benzene are sp2 hybridized. The two sp2 hybrid orbitals of each carbon atom overlap with the sp2 hybrid orbitals of adjacent carbon atoms to form six sigma bonds in the hexagonal plane.
The remaining sp2 hybrid orbital on each carbon atom overlaps with the s-orbital of hydrogen to form six sigma C-H bonds. The remaining unhybridized p-orbital of carbon atoms has the possibility of forming three it bonds.

Question 4.
Account for the following:
(i) The hydroxides and carbonates of sodium and potassium are easily soluble in water while the corresponding salts of magnesium and calcium are sparingly soluble in water.
(ii) Potassium and caesium rather than lithium are used in photoelectric cells.
(iii) Lithium is a strong reducing agent in aqueous solution.
OR
Write balanced equations for chemical reactions between the following:
(i) Na2O2 and water
(ii) KO2 and water
(iii) Na2O and CO2.
Answer:
(i) The solubility of a salt in water depends upon their lattice energy and hydration energy.
In the case of hydroxide and carbonates of sodium and potassium, their hydration energy is more than their lattice energy.

Therefore, they dissolve in water. In the case of hydroxides and carbonates of magnesium and calcium, their hydration energy is less than their lattice energy. Therefore, they are sparingly soluble.

(ii) Due to low ionisation enthalpy, potassium and caesium eject electrons when exposed to light while lithium has the highest ionization enthalpy due to which it cannot be used in photoelectric cells.

(iii) The ionic size of lithium is small so it has highest hydration enthalpy. Ionisation energy of Li is highest among alkali metals but hydration enthalpy predominates over ionisation enthalpy, Thus, lithium has strong reducing power in aqueous solution.

Question 5.
Answer the following questions:
(i) If two substances are in equilibrium in a reversible reaction and if the concentration of each reactant is reduced to half, then how the equilibrium constant will be affected?
(ii)
(a) Fizz is observed when soda water bottle is opened. Why?
(b) For an exothermic reaction, what happens to the equilibrium constant if temperature is increased?
OR
(i) A sparingly soluble salt having general formula Ap+x Bq-y and molar solubility S is in equilibrium with its saturated solution. What will be the relationship between solubility and solubility product of such salt?
(ii) (a) State Le-Chatelier’s principle.
(b) For the given reaction CO(g) + 2H2(g) ⇌ CH3OH(g), ∆rH° = – 92 kj/mol, predict the direction of the reaction where:
(1) pressure is doubled
(2) temperature is doubled.
Answer:
(i) The equilibrium constant of a reaction is the ratio of the concentration of products to the concentration of reactants at equilibrium. It is a measure of the extent of the reaction. It is independent of the rate of reaction and initial concentrations of reactants and products but depends on the temperature and pressure. Hence, Keq is not affected by change in concentration of reactants and products.

(ii)
(a) An unopened soda water bottle is virtually bubble-free because the pressure inside the bottle keeps the carbon dioxide dissolved in the liquid. When it is opened, pressure is released and the gas bubbles are allowed to wiggle free from the liquid and rise to the surface in the form of fizz.

(b) Equilibrium constant, K = \(\frac{\mathrm{K}_{f}}{\mathrm{~K}_{b}}\)
In exothermic reaction, with the increase in temperature, equilibrium constant for backward reaction (Kb) increases much more than Kf. Thus, equilibrium constant (K) decreases with increase in temperature for an exothermic reaction.

OR
(i) A sparingly soluble salt having general formula Axp+’ Byq-, its molar solubility is S mol L-1
Then, Axp+’ Byq- ⇌ xAp+(aq) +yBq-(aq)
S moles of AxBy dissolve to give x moles of Ap+ and y moles of Bq-.
Therefore, solubility product
Ksp= [Ap+]x[Bq-]y
= [xS]x[yS]y
= xxyySx+y

(ii) (a) According to Le – Chatelie’s principle, “A change in any of the factors that determine the equilibrium conditions of a system will cause the system to change in such a manner so as to reduce or to counteract the effect of the change”.

(b) CO(g) + 2H2(g) ⇌ CH3OH(g),
ΔrH0 = -92 kJ/mol

(1) When pressure is doubled, the equilibrium will shift in the direction where volume decreases i.e. forward direction.
(2) When temperature is doubled, the equilibrium will shift in backward direction because it is an exothermic reaction ΔH <O.

Question 6.
Account for the following:
(i) PbCl4 is less stable than SnCl4 but PbCl2 is more stable than SnCl2.
(ii) Carbon shows maximum catenation in Group 14 elements.
(iii) Diamond is covalent, yet it has high melting point.
Answer:
(i) Stability of +4 oxidation state decreases down the group while that of +2 oxidation state increases due to inert pair effect. Thus, PbCl2 and SnCl4 are more stable than PbCl4 and SnCl2 respectively.
(ii) Due to strong C-C bond, its bond dissociation energy is the highest among Group 14 elements.
(iii) Diamond has three dimensional network structure involving strong C-C bonds. These bonds are difficult to break. Hence, the melting point of diamond is very high.

Question 7.
Determine the degree of ionisation and pH of a 0.05 M of ammonia solution. The ionisation constant of ammonia is 1.77 x 10-5. Also calculate the ionisation constant of conjugate add of ammonia.
Answer:
Given,
Kb = 1.77 x 10-5
C =0.05 M
The ionisation of NH3 in water is represented by the equation:
CBSE Sample Papers for Class 11 Chemistry Term 2 Set 2 with Solutions 8
where, α = Degree of ionization
C = concentration of solution
Ionization constant of ammonia,

Kb\(\frac{\left[\mathrm{NH}_{4}^{+}\right]\left[\mathrm{OH}^{-}\right]}{\left[\mathrm{NH}_{3}\right]} \)
or α = \(\sqrt{\frac{\mathrm{K}_{\mathrm{b}}}{\mathrm{C}}}\)
= \(\frac{\mathrm{C} \alpha \cdot \mathrm{C} \alpha}{\mathrm{C}(1-\alpha)}\)
= \(\frac{\mathrm{C} \alpha^{2}}{(1-\alpha)}\)

The value of α is small, so, the equation can be simplified by neglecting a in comparison to 1 in the denominator on right hand side of the equation.
∴ Kb = Cα2
or α = \(\sqrt{\frac{\mathrm{K}_{\mathrm{b}}}{\mathrm{C}}}\)
= \(\sqrt{\frac{1.77 \times 10^{-5}}{0.05}}\)
= 0.018

[OH] = Cα
= 0.05 x 0.018
= 9.4 x 10-4 M
∵ Ionisation product of water,
[H+] [OH] = Kw
[H+] = \(\frac{\mathrm{K}_{\mathrm{w}}}{\left[\mathrm{OH}^{-}\right]}=\frac{10^{-14}}{9.4 \times 10^{-4}}\)
= 1.06 x 10-11M
Now, pH=-log10[H+]
= -log (1.06 x 10-11)
= -log 1.06 + 11 log 10
= -0.0253 + 11
= 10.9747

Now, using the relation for conjugate acid base pair,
Ka x Kb = Kw
Ka = \(\frac{\mathrm{K}_{\mathrm{w}}}{\mathrm{K}_{\mathrm{b}}}\)
= \(\frac{10^{-14}}{1.77 \times 10^{-5}}\)
=5.64 x 10-10

CBSE Sample Papers for Class 11 Chemistry Term 2 Set 2 with Solutions 13
(i) Which curve in figure represents the curve of ideal gas?
(ii) State the law followed by the curve B.
(iii) What are the conditions on the application of which a gas deviates from ideal behaviour?
Answer:
(i) Given,
P =3.32 bar,
V = 5 dm3
R = 0.083 bar dm3 K-1 mol-1
n =4 moIes
By Ideal gas equation,
PV = nRT

T = \(\frac{\mathrm{PV}}{n \mathrm{R}}=\frac{3.32 \times 5}{4 \times 0.083}=\frac{16.6}{0.332}\)
T = 50 k
(ii) No. of moles in 1.4 g of N2 gas = \(\frac{\text { Given mass }}{\text { Molar mass }} \)
= \(\frac{1.4}{28}=\frac{1}{20}\) = 0.05 mol

Total number of electrons present in 0.05 moles of N2,
= 0.05 x 6.02 x 1023 x 14
= 4.214 x 1023 electrons

(iii) All gases obey Charle’s law at very low pressure and high temperature.
OR
(i) Curve B represents for ideal gas. For ideal gas, pV = constant is represented by straight line. Therefore, only B represents the curve of ideal gas.

(ii) The ideal gas follows Boyle’s law. For ideal gas, PV = constant represented by straight line. Therefore, Boyle’s law states that the pressure (p) of a given quantity of gas varies inversely with its volume (V) at constant temperature i.e., in mathematical expression, pV = k, a constant.

(iii) Gases deviate from ideal behaviour under high pressure and low temperatures because the intermolecular forces come into play as gas particles come close to each other by action of high pressure and low temperature.

Question 12.
Read the passage given below and answer the questions that follow:
Hydrocarbons are of different types. Saturated hydrocarbons contain carbon-carbon and carbon- hydrogen single bonds. Unsaturated hydrocarbons contain carbon-carbon multiple bonds – double bonds, triple bonds or both. Aromatic hydrocarbons are a special type of cyclic compounds that are also known as ‘arenes’. Most of such compounds were found to contain benzene ring.

Now, the name is applied to all the ring systems whether or not having benzene ring, possessing planarity, complete delocalisation of the electrons in the ring, following Huckel rule. Aromatic hydrocarbons are non¬polar molecules and are usually colourless liquids or solids with a characteristic aroma. Arenes are characterised by electrophilic substitution reactions.
(i) Ethyne on passing through red hot iron tube at 873 K undergoes cyclic polymerisation. Name the product formed in this reaction.
(ii) Write the chemical reaction for conversion of benzene into BHC.
(iii) Examine the following and select the aromatic structures.

(iv) How does the presence of halogen atom affect the reactivity of benzene ring towards electrophilic substituition reaction?
OR
Write name and structure of any two arenes.
Answer:
(i) In cyclic polymerisation, three molecules of ethyne polymerise to form benzene.

(iii) In (A) part, ring is planar and follow (4n+2) π-electrons rule i.e., Huckel’s rule.
Here,n=0.

(iv) For an electrophilic substitution reaction, the presence of halogen atom in the benzene ring deactivates the ring by inductive effect (-I effect) and increases the charge density at ortho- and para-position relative to meta-position by resonance. When chlorine is attached to benzene ring, chlorine being more electronegative pulls the electrons because of its -I effect. The electron cloud of benzene becomes less dense.

Thus, chlorine makes the benzene ring in aryl halide somewhat deactivated. But due to resonance, the electron density on ortho- and para-position is greater than on meta-position.

Section-A

Question 1.
Attempt any two:
(i) Define physical equilibrium. Give an example also.
(ii) Define chemical equilibrium. Give an example.
(iii) Why is chemical equilibrium called dynamic equilibrium?
Answer:
(i) A physical equilibrium is a system whose physical state does not change when dynamic equilibrium is reached.
e.g., Solid ↔ liquid.
(ii) A chemical equilibrium is a system whose chemical composition of the system does not change when dynamic equilibrium is reached.
e.g., N2(g) + 3H2(g) ↔ 2NH3(g)

(iii) Chemical equilibrium is achieved when the rate of forward and backward reaction becomes equal. Although overall it is in equilibrium but inside the forward reaction and backward reaction both occur and so there is motion in the atomic and molecular level. Dynamic refers to anything having motion. Since the equilibrium is not static so, the chemical equilibrium is called dynamic equilibrium.

Question 2.
What will be the minimum pressure required to compress 500 dm3 of air at 1 bar to 200 dm3 at 30°C?
Answer:
Given,
P1= 1 bar
P2=?
V1 = 500dm3
V2 = 200dm3
Temperature remains constant at 30°C.

∴ According to Boyle’s law,
P1V1 = P2V2
1 x 500=P2 x 200
P2 = 2.5bar

Question 3.
Give reasons to support your answer:
(i) Alkali metals should be stored in kerosene oil.
(ii) Lithium is kept wrapped in paraffin wax and not stored in kerosene.
Answer:
(i) The alkali metals tarnish in air due to the formation of oxide at their surface and hence they are stored in kerosene oil.

Question 4.
Account for the following:
(i) Benzene undergo electrophilic substitution reactions easily but nucleophilic substitutions with difficulty.
(ii) Rotation around carbon-carbon single bond of ethane is not completely free.
(iii) Halogens are o- and p-directing in haloarenes despite their -I effect.
OR
How will the following conversions take place? Give chemical reaction of each of the following.
(i) Ethyne into benzene.
(ii) Propene to propane-l-ol.
(iii) Benzene to m-nitrochlorobenzene
Answer:
(i) Benzene is a planar molecule having delocalized electrons above and below the plane of ring. Hence, it is electron-rich compound. As a result, it is highly attractive towards electron-deficient species i.e., electrophiles. Therefore, it undergoes electrophilic substitution reactions very easily. Nucleophiles are electron-rich in nature. Hence, they are repelled by nucleophilic character of benzene. Hence, benzene undergoes nucleophilic substitutions with difficulty.

(ii) Ethane contains a carbon-carbon sigma (σ) bond. Electron distribution of the sigma molecular orbital is symmetrical around the internuclear axis of the C-C bond which is not disturbed due to rotation about its axis. This permits free rotation around a C-C single bond. However, rotation around a C-C single bond is not completely free. It is hindered by a small energy barrier due to weak repulsive interaction between the adjacent bonds.

Such a type of repulsive interaction is called torsional strain. From all the conformations of ethane, the staggered form has the least torsional strain and the eclipsed form has the maximum torsional strain. The energy difference between the two extreme forms is of the order of, 12.5 kJ mol-1, which is very small. It has not been possible to separate and isolate different conformational isomers of ethane.

(iii) In case of aryl halides, halogens are little deactivating because of their strong -I effect. Therefore, overall electron density on the benzene ring decreases. In other words, halogens are deactivating due to -I effect. However, because of the + R-effect, i.e., participation of lone pairs of electrons on the halogen atom with the π-electrons of the benzene ring, the electron density increases more at o- and p-positions than at m-positions. As a result, halogens are o-, p-directing. The combined result of + R-effect and -I-effect of halogens is that halogens are deactivating but o, p-directing.

Question 5.
Answer the following questions:
(i) Under what conditions is the heat absorbed by a system is equal to the work done by the system?
(ii) Under what conditions the following reaction will be spontaneous:
(a) Reaction with both ΔH and ΔS positive.
(b) Reaction with both ΔH and ΔS negative.
OR
(i) What is enthalpy change at constant volume? Explain.
(ii) Calculate the enthalpy of transition for carbon from the following data given:
Cdiamond + O2 → CO2(g); ΔH = – 943 kcal
Camorphous + O2 → CO2(g); ΔH = – 97-6 kcal
Also, calculate the heat required to change 1 g of Cdiamond to Camorphous.
Answer:
By First law of thermodynamics,
ΔU = q+w
(i) For an ideal gas, undergoing an isothermal
change, ΔU = O. Hence,
q=-W
i.e., the heat absorbed by the system is equal to work done by the system.

(ii)
(a) If ΔG = ΔH – TΔS <O, then reaction is spontaneous. Then, the reaction will be spontaneous, if TΔS > ΔH.
Therefore, the reaction with both ΔH and ΔS positive will be spontaneous at sufficiently high temperatures.

(b) if both ΔH and ΔS are negative, that means – TΔS will become positive and the reaction will be spontaneous at low temperature, where, ΔG will be negative.
ΔG=-ΔH+TΔS < O

OR
(i) When reaction is carried out in a closed vessel so that volume remains constant, i.e., ΔV = O, then qu = ΔU or ΔH = ΔU. This is known as enthalpy change at constant volume.

(ii) Heat of transition of Cdiamond to Camorphous
Cdiamond +O2 → CO2(g)
Δ H= -94.3 kcal ………………………. (1)
Camorphous+O2 → CO2(g)
ΔH=-97.6kcal ……………………………… (2)
Subtract equation (2) from (1), we get
Cdiamond– Camorphous = – 943- (-976) = 3.3kcal

This heat represents the transformation of 1-mole Cdiamond to Camorphous.
Therefore, heat of transformation for 1 g of Cdiamond to 1g Camorphous = 33 kcal/12
= 0.275 kcal

Question 6.
Account for the following:
(i) BCl3 is more stable as compared to TICl3.
(ii) Boron trifluoride behaves as a Lewis acid.
(iii) The B-F bond lengths in BF3 (130 pm) and BF4(143 pm) differ.
Answer:
(i) Thallium and boron belong to group 13 of the periodic table and +1 oxidation state becomes more stable as we move down the group. Boron is more stable than thallium because +3 state of thallium is highly oxidizing and it reverts back to more stable +1 state.

(ii) The electronic configuration of boron is ns2np1. It contains three electrons in its valence shell. Thus, it can form only three covalent bonds which means there are only six electrons around boron and its octet remains incomplete. When a boron atom combines wits three fluorine atoms, its octet remains incomplete. Therefore, boron trifluoride remains electron-deficient and acts as lewis acid.

(iii) The B-F bond length in BF3 is shorter than the B-F bond length in BF4. BF3 is an electron-deficient species. With a vacant p-orbital on boron, the fluorine and boron atoms undergo pπ-pπ back-bonding to remove this deficiency. This imparts a double bond character to the B-F bond. This double-bond character causes the bond length to shorten in BF3 (130 pm). However, when BF3 coordinates with the fluoride ion, a change in hybridization from sp2 (in BF3) to sp3 (in BF4) occurs. Boron now forms 4σ bonds and the double-bond character is lost. This accounts for a B-F bond length of 143 pm in BF4 ion.

Question 7.
When 13.8 g of N2O4 was placed in a 1L reaction vessel at 400 K and allowed to attain equilibrium, the total pressure at equilibrium was found to be 9.15 bar. Calculate Kc, Kp, and partial pressure at equilibrium.
N2O4(g) ⇌ 2NO2(g).
Answer:
Given,
Total volume (V) = 1L
Mass of N2O4 = 13.8g
Molar mass of N2O4 = 14 x 2 + 16 x 4 = 92g
Number of moles of N2O4(n) = \(\frac{\text { Given mass }}{\text { Molar mass }} \)
= \(\frac{13.89}{92 g}\)
= 0.15 mol

Gas constant (R) = 0.083 bar L mol-1 K-1
Temperature (T) = 400 K
According to ideal gas equation,
PV = nRT
p x 1 L = 0.15 mol x 0.083 bar L mol-1 K-1 x 400K
∴ p = 4.98bar

For the given reaction,
CBSE Sample Papers for Class 11 Chemistry Term 2 Set 1 with Solutions 7
Hence,
Ptotal at equilibrium = pN2O4 + pNO2
9.15 =(4.98-x) + 2x
9.15 =4.98 + x
∴ x =9.15-4.98 = 4.17 bar

Partial pressures at equilibrium are,
pN2O4=4.98-4.17 = 0.81 bar
pNO2 =2x = 2 X 4.17 = 8.34bar
Kp = \(\frac{\left(p_{\mathrm{NO}_{2}}\right)^{2}}{p_{\mathrm{N}_{2} \mathrm{O}_{4}}}\)
= \(\frac{(8.34)^{2}}{0.81}\)
= 85.87

Kp’ =Kc(0.083 x 400)1
∴Kc = \(\frac{85.87}{0.083 \times 400}\)
=2586≈2.6

(i) What is the difference between the two structures?
(ii) What would be the physical state of BeCl2 in figure 1 and 2?
(iii) Why does Be not exhibit a coordination number more than four?
Answer:
(i) The alkaline earth metals cannot be obtained by reduction of their oxides because the enthalpies of formation of these oxides are quite high and consequently they are very stable to heat.

(ii) Beryffium and magnesium do not impart colour to the flame in the flame test due to the small size of Be and Mg atoms. So, these atoms require high excitation energy and are not excited by the energy of the flame.

(iii) Cesium is the most electropositive alkali metal because the attraction of nucleus of cesium is very less towards the outermost electron, so it is likely to lose its electron, easily to attain stable noble gas configuration.

Lithium-ion has the smallest size ion due to more effective nuclear charge. Thus, lithium-ion is heavily hydrated that rest element ions of the Group 1. So, Li + has lowest mobility.

Question 12.
Read the passage given below and answer the questions that follow:
Boyle’s law can be used to describe the effects of altitude on gases in closed cavities within the body, and to calculate the total intra-thoracic gas volume by body plethysmography. As altitude increases, ambient pressure decreases, and therefore, by Boyle’s law, volume expansion occurs in enclosed spaces. This effect can be demonstrated by observing the expansion of a sealed bag of potato chips on an ascending commercial flight.

In one artificial pneumothorax model, a 40 mL pneumothorax increased in volume by up to 16% at 1.5 km (approx. 5000 feet) from sea level, an effect which may prompt thoracostomy before helicopter transfer to prevent transition to a tension pneumothorax. It is estimated that an expansion of up to 30% for a closed volume of gas in the human body, e.g., a bulla, can be expected after ascending from sea level to an altitude of 2.5 km (approx. 8200 feet).

Boyle’s law also explains the use of saline in the cuff of an endotracheal tube during hyperbaric therapy;
to prevent an air leak due to the reduction of volume as pressure increases. When ascending from, depth, if .a diver holds their breath, the gases in their lungs will expand and can cause barotrauma, arterial gas embolism, mediastinal emphysema, or even pneumothorax.
(i) How will you explain the expansion of a sealed packet of chips on a flight which is taking off?
(ii) When the graph of pressure is plotted against volume at different temperatures, a curve is obtained. Identify the curve that corresponds to the constant temperature.
(iii) What does the higher curves in the above-mentioned graph correspond to? Explain with graphical representation?
(iv) Density of a gas is found to be 5.46 g/dm3 at 27°C, 2 bar pressure. What will be its density at STP condition?

(ii) P – V graph at different values of constant temperature are hyperbolic curves. The curves which correspond to constant temperature are called isotherms.

(iii) According to Boyle’s law
PV =k1
