Vedclass · Answer

(A) Adsorption is a spontaneous process where gas molecules are trapped on a solid surface, leading to a decrease in the randomness of the system. Thus, $\Delta S Since the process is spontaneous, the Gibbs free energy change must be negative $(\Delta G From the equation $\Delta G = \Delta H - T\Delta S$, for $\Delta G$ to be negative when $\Delta S$ is negative, $\Delta H$ must be negative. Therefore, the process is exothermic $(\Delta H < 0)$.
