Vedclass · Answer

(B) The extent of adsorption of a gas on a solid adsorbent depends on the ease of liquefaction of the gas. Easily liquefiable gases have higher critical temperatures $(T_c)$ and stronger van der Waals forces of attraction,leading to greater adsorption. The critical temperatures $(T_c)$ of the given gases are: $SO_2$ $(430 \ K)$ > $O_2$ $(154 \ K)$ > $N_2$ $(126 \ K)$ > $H_2$ $(33 \ K)$. Since $SO_2$ has the highest critical temperature,it is the most easily liquefiable and thus adsorbed to the greatest extent.

Which of the following gases is adsorbed to a greater extent if the adsorbent remains the same under similar conditions of temperature and pressure?
