$NH_3$

Vedclass · Answer

(D) The extent of adsorption of a gas on a solid surface depends on the ease of liquefaction of the gas. Easily liquefiable gases have higher critical temperatures $(T_c)$ and are adsorbed more strongly. The critical temperatures of the given gases are: $H_2$ $(33 \ K)$,$CO$ $(134 \ K)$,$CO_2$ $(304 \ K)$,and $NH_3$ $(405 \ K)$. Since $NH_3$ has the highest critical temperature,it is the most easily liquefiable and will be adsorbed to the greatest extent on the surface of charcoal.

Which of the following gases will be adsorbed to a greater extent on the surface of charcoal?
