Statement 1: For adsorption, ΔG is negative.Statement 2: Adsorption is an exothermic process accompanied by decrease in randomness.

We know that ΔG=ΔH−TΔSSince, adsorption is exothermic, so ΔH=−ve further, it occurs with decrease in randomness, so ΔS=(−)ve              ΔG=−ve−T(−ve)=−ve+TSo, at low temperature ΔG=− ve.
