Adsorption is spontaneous and proceeds with decrease in entropy. Hence, which is correct representation of variation of xm with pressure at different temperature?

Adsorption is spontaneous, thus ∆G<0It proceeds with decrease in entropy, thus ∆S<0Since,           ΔG=ΔH−TΔS          ΔH=(ΔG+TΔS)          ΔG and ΔS beìng <0Thus, ΔH<0By Le-Chatelier's principle, increase in temperature, decreasesadsorption. Also xm ∝ p, but extent of adsorption decreasesas T increases.
