Vedclass · Answer

(D) The extent of adsorption of a gas on a solid surface (adsorbent) is influenced by several factors:$1$. Nature of the gas: Easily liquefiable gases (like $NH_3$,$HCl$,$CO_2$) are adsorbed more readily than permanent gases (like $H_2$,$O_2$,$N_2$).$2$. Pressure of the gas: According to the Freundlich adsorption isotherm,the extent of adsorption $(x/m)$ increases with an increase in pressure.$3$. Temperature of the system: Adsorption is generally an exothermic process; therefore,according to Le Chatelier's principle,the extent of adsorption decreases with an increase in temperature.Thus,all the given factors affect the extent of adsorption.
