Vedclass · Answer

(D) $A.$ Incorrect. Water vapours are absorbed by anhydrous calcium chloride,not adsorbed.$B.$ Correct. Adsorption is a spontaneous process,and surface energy decreases as the surface area available for adsorption decreases.$C.$ Incorrect. As adsorption proceeds,the surface becomes covered,and the heat released per unit of adsorption decreases,so $\Delta H$ becomes less and less negative.$D.$ Correct. Adsorption restricts the movement of gas molecules,leading to a decrease in the entropy of the system.Therefore,there are $2$ incorrect statements ($A$ and $C$).
