Q:

For a certain reaction,DGq = -45 kJ/mol and DHq= -90 kJ/mol at 0°C. What is the minimum temperature at which the reaction will become spontaneous, ifDHq and DSq are independent of temperature?

A) 273 K B) 298 K
C) 546 K D) 596 K
 
Answer & Explanation Answer: C) 546 K

Explanation:

T = 273 °K

Using the formula,

DGq = DHq –TDS

-45 = -90 –273 DS

DS = 0.164

Now since DHq and DSq are independent,T2= DH/DS = 45/0.164 = 273°K

Required Temp = 273 + 273 = 546°K

Q:

A passage is given with 5 questions following it. Read the passage carefully and choose the best answer to each question out of the four alternatives.


The quest to find life outside the solar system got a big boost with the discovery of seven Earth-size extra-solar planets, or exoplanets, orbiting a dwarf star about 40 light years away. Unlike earlier discoveries of exoplanets, all seven planets could possibly have liquid water — a key to life as we know it on Earth — with three planets having the greatest chance. This is by far the largest collection of Earth-like planets in the habitable 'Goldilocks' zone of a star — neither too close nor too far from a star, which raises the possibility of liquid water being present on the surface. Only Earth has liquid water in the solar system. Since the dwarf star is much cooler than the Sun, the dimming of light each time a planet passes or transits before the star could be easily recorded from Earth unlike in cases when planets transit a Sun-like bright star. Since the initial discovery of three planets was made using the Chile-based Transiting Planets and Planetesimals Small Telescope, the exoplanet system is called TRAPPIST-1.

 

What is essential to have the possibility of life on a planet?

A) Presence of atmosphere B) Presence of gravity
C) Presence of sunlight D) Presence of liquid water
 
Answer & Explanation Answer: D) Presence of liquid water

Fever in the season of dengue is sending Calcuttans scurrying to hospitals for admission, triggering a shortage of beds that has forced some private health care institutes to even postpone planned surgeries. Apollo Gleneagles Hospitals on the Bypass had 504 patients in its care as on Thursday of whom 70 had been admitted with fever. Belle Vue Clinic had 180 patients, 32 of them with dengue. Calcutta Medical Research Institute had 350 patients 60 of them with fever.

The number of people admitted for treatment of fever caused by dengue or any undiagnosed illness has been rising every day across hospitals for more than a fortnight.

"There has been heavy pressure on all private hospitals for admission of dengue and cases of unknown fever since the beginning of August. Now it is a surge," said Pradip Tondon, President of the Association of Hospitals of Eastern India.

In July, four to five patients were getting admitted with fever on an average in every hospital. The number has since ballooned with the Calcutta Municipal Corporation apparently in denial about the extent of the dengue outbreak and the Government focused on playing down the threat.

Such has been the rush of patients with fever that some hospitals are calling up people to postpone admissions planned in advance, mostly for surgeries. "We have told many people to come only when we call them to confirm availability of beds," said an official at Belle Vue.


The Government's "playing down the threat" means

A) refusing to acknowledge the danger B) refusing to play with the threat
C) playing and threatening D) putting down the threat
 
Answer & Explanation Answer: A) refusing to acknowledge the danger
