Vedclass · Answer

(C) The extent of adsorption of a gas on a solid surface depends on the critical temperature $(T_c)$ of the gas. Easily liquefiable gases (gases with higher $T_c$) are adsorbed more readily. The critical temperatures of the given gases are: $NH_3$ $(405.5 \ K)$,$CO_2$ $(304.1 \ K)$,and $H_2$ $(33.2 \ K)$. Since the order of critical temperatures is $NH_3 > CO_2 > H_2$,the order of adsorption will also be $NH_3 > CO_2 > H_2$.

The correct order of the volume of $NH_3, CO_2$,and $H_2$ gases adsorbed on $1 \ g$ of charcoal at $300 \ K$ is:
