If both the Assertion and Reason are incorrect.

(D) The Assertion is incorrect because physical adsorption is a surface phenomenon,but the term used in the assertion is 'absorption',which is a bulk phenomenon.Furthermore,the Reason is incorrect because physical adsorption involves weak van der Waals forces and does not involve the breaking of chemical bonds.Therefore,both the Assertion and the Reason are incorrect.

View Solution

Given below are two statements. One is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A :$ Activated charcoal adsorbs $SO_{2}$ more efficiently than $CH_{4}$.
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.
