Vedclass · Answer

(B) Chemical adsorption is an exothermic process,so the enthalpy change $(\Delta H)$ is negative $(\Delta H Since the gas molecules are adsorbed on the solid surface,their randomness decreases,leading to a decrease in entropy $(\Delta S For a spontaneous process,the Gibbs free energy change $(\Delta G)$ must be negative $(\Delta G < 0)$.
