Vedclass · Answer

(B) Physisorption is an exothermic process,which can be represented as: Adsorbate + Adsorbent $\rightleftharpoons$ Adsorption Complex + Heat. According to Le Chatelier's principle,for an exothermic process,an increase in temperature shifts the equilibrium in the backward direction. Therefore,the extent of physical adsorption decreases with an increase in temperature.
