Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: Activated charcoal adsorbs $\mathrm{SO_2}$ more efficiently than $\mathrm{CH_4}$ .

Reason R: Gases with lower critical temperatures are readily adsorbed by activated charcoal.

In the light of the above statements, choose the correct answer from the options given below.

Both A and R are correct and R is the correct explanation of A.

Both A and R are correct but R is NOT the correct explanation of A.

A is correct but R is not correct.

A is not correct but R is correct.

Answer and worked solution

Official answer: C

Assertion. $\mathrm{SO_2}$ (critical temperature 430 K) is adsorbed more than $\mathrm{CH_4}$ (190 K). Correct.

Reason. It is gases with higher critical temperatures that are readily adsorbed. Not correct.
