JEE Main 2023 — Surface Chemistry Question with Solution

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

Assertion A: Amongst $$\mathrm{He},\mathrm{Ne},\mathrm{Ar}$$ and $$\mathrm{Kr}$$; 1$$\mathrm{g}$$ of activated charcoal adsorbs more of $$\mathrm{Kr}$$.

Reason R: The critical volume $${\mathrm{V}}_{\mathrm{c}}\left({\mathrm{cm}}^3{\mathrm{mol}}^{-1}\right)$$ and critical pressure $${\mathrm{P}}_{\mathrm{c}}$$ (atm) is highest for Krypton but the compressibility factor at critical point $${\mathrm{Z}}_{\mathrm{c}}$$ is lowest for Krypton.

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