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 $(\Delta H < 0)$.
