This causes a decrease in the surfaceenergy of the adsorbent. Therefore,adsorption is always exothermic. ... When a gas is adsorbed on a solid surface, its movement is restricted leading to a decrease in the entropy of the gas i.e., ΔS is negative. Now for aprocess to be spontaneous, ΔG should be negative.
