Question

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

Reason R : Gases with lower critical temperatures are readily adsorbed by activated charcoal.
In light of the above statements, choose the correct answer from the options given below.

Options

• 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 1

A is correct but R is not correct.

Explanation:

Due to polar nature of SO₂, it has a higher critical temperature than CH₄. Activated charcoal adsorbs SO₂ more efficiently than CH₄ due to more intermolecular attraction forces in SO₂.
