JEE · NEET Previous Year Question
Which of the following statements is correct for the spontaneous adsorption of a gas?
Topic: NEET PYQ
Answer: B. Full step-by-step solution below.
- A is negative and, therefore should be highly positive.
- B is negative and therefore, should be highly negative.
- C is positive and therefore, should be negative.
- D is positive and therefore, should also be highly positive.
Correct answer: B
Solution
(b) Using Gibb’s‐Helmholtz equation,During adsorption of a gas, entropy decreases i.e.
For spontaneous adsorption, should be negative, which is possible when is highly negative.
