Why adsorption is always exothermic?

Description : Why adsorption is always exothermic?

Last Answer : Ans.: In Adsorption, change of entropy ΔS is –ve i.e. non favourable condition for exothermic change where as change of enthalpy ΔH is –ve i.e. favourable condition for exothermic change. Overall ΔG becomes –ve in adsorption; therefore adsorption is always exothermic.
