Vedclass · Answer

(A) The extent of adsorption of a gas on a solid adsorbent like activated charcoal depends on the ease of liquefaction of the gas.Easily liquefiable gases (which have higher critical temperatures) are adsorbed more strongly.Among the given options,$CO_2$ has the highest critical temperature $(304.1 \ K)$ compared to $CH_4$ $(190.6 \ K)$,$N_2$ $(126.2 \ K)$,and $H_2$ $(33.2 \ K)$.Therefore,$CO_2$ is adsorbed to the maximum extent.

Which of the following gases is adsorbed to the maximum extent by activated charcoal?
