Given below are two statement: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A)

S{O_2}(g)

is adsorbed to a large extent than

{H_2}(g)

on activated charcoal.
Reason (R)

S{O_2}(g)

has a higher critical temperature than

{H_2}(g)

In the light of the above statements, choose the most appropriate answer from the options given below

View answer and explanation

Correct option: B

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

Option B (Both A and R are correct and R is the correct explanation of A) is correct because SO2 has a higher critical temperature than H2, indicating stronger intermolecular forces, which leads to greater adsorption on activated charcoal.

If for the gases, the critical temperatures are mentioned below i.e.

\begin{array}{cccccccccccccccccccc} {\underline {{\text{Gas}}} }&{\underline {\,{\text{Critical}}\,\,{\text{temperature}}} } \\ {\text{A}}&{{T_{{C_1}}}} \\ {\text{B}}&{{T_{{C_2}}}} \\ {\text{C}}&{{T_{{C_3}}}} \\ {\text{D}}&{{T_{{C_4}}}} \end{array}

{T_{{C_1}}} > {T_{{C_2}}} > {T_{{C_3}}} > {T_{{C_4}}}
