Q. Which one of the following statements is incorrect?
A) Adsorption always leads to a decrease in enthalpy and entropy of the system
B) Adsorption arises due to unsaturation of valence forces of atoms or molecules on the surface
C) Adsorption increases with rise in the temperature
D) Adsorption decreases the surface energy
Explanation
(c)
When temperature increases, the adsorbed molecules get energy and desorption starts increasing, therefore adsorption decreases with increase in temperature
