Vedclass · Answer

(C) Adsorption is a surface phenomenon where gas molecules are trapped on the surface of a solid. When gas molecules are adsorbed,their freedom of movement is restricted,which leads to a decrease in the entropy of the system $(\Delta S For a process to be spontaneous,the Gibbs free energy change $(\Delta G)$ must be negative $(\Delta G = \Delta H - T\Delta S Since $\Delta S$ is negative,the term $-T\Delta S$ becomes positive. For $\Delta G$ to be negative,$\Delta H$ must be negative,which means the process is exothermic.
