At the equilibrium position in the process of adsorption …………

A

`Delta H gt 0`

B

`Delta H=T Delta S`

C

`Delta H gt T Delta S`

D

`Delta H lt T Delta S`

Text Solution

Verified by Experts

The correct Answer is:
B
As we know that, at equilibrium `Delta G=0`
`" " Delta H-T Delta S=0`
` " " Delta H=T Delta S`
Hence, at equilibrium change is equal is equal to product of temperature and entropy change.
