Vedclass · Answer

(B) Physical adsorption is an exothermic process. According to Le Chatelier's Principle,for an exothermic process,an increase in temperature favors the reverse process (desorption). Therefore,physical adsorption decreases with an increase in temperature. For a process to be spontaneous,the Gibbs free energy change $\Delta G$ must be negative. Since $\Delta G = \Delta H - T\Delta S$,and adsorption involves a decrease in entropy $(\Delta S  |T\Delta S|$.
