Question
The following statements relate to the adsorption of gases on a solid surface. Identify the incorrect statement among them :
Options
A.On adsorption decrease in surface energy appears as heat
B.Enthalpy of adsorption is negative
C.On adsorption, the residual forces on the surface are increased
D.Entropy of adsorption is negative
Solution
Adsorption takes place due to the presence of residual forces on the surface. After adsorption, these are
decreased.
