The number of incorrect statement/s from the following is/are A. Water vapours are adsorbed by anhydrous calcium chloride. B. There is a decrease in surface energy during adsorption. C. As the adsorption proceeds, ΔH becomes more and more negative. D. Adsorption is accompanied by decrease in entropy of the system.

Correct answer

2

Step-by-step solution

Water vapours are absorbed by anhydrous calcium chloride. There is a decrease in surface energy during adsorption. As the adsorption proceeds, ΔH becomes more and more negative. Adsorption is accompanied by decrease in entropy of the system. Thus, option A and C are incorrect.
