Which one of the following is not applicable to the phenomenon of adsorption?

A

`DeltaH gt 0`

B

`DeltaG lt 0`

C

`deltaS,0`

D

`DeltaH lt 0`

Text Solution

Verified by Experts

The correct Answer is:
A
For phenomenon of adsorption 0, `DeltaH<0` i.e., enthalpy change during phenomenon of adsorption is negative because during adsorption, there is always a decrease in residual forces of the surface which lead to decrease in surface energy which appears as heat. So, adsorption is an exothermic process and `DeltaH <0`
