Easy MCQ +4 / -1 PYQ · JEE Mains 2022

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

Assertion A : Activated charcoal adsorbs SO2 more efficiently than CH4.

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.

  1. A Both A and R are correct and R is the correct explanation of A.
  2. B Both A and R are correct but R is NOT the correct explanation of A.
  3. C A is correct but R is not correct. Correct answer
  4. D A is not correct but R is correct.
