For adsorption, the thermodynamic requirement is that

A

`Delta H` must be negative

B

`Delta S` must be negative

C

`Delta G` must be negative

D

`Delta H,DeltaS and Delta G` must be negative

Text Solution

Verified by Experts

On the basis of equation, `Delta G=Delta H-T Delta S`can be negative if `Delta H` has sufficiently high negative value as –T`Delta H` is positive. Thus, in adsorption which is a spontaneous process.
`Delta S` is negative
`Delta S` is sufficiently negative and as a result `Delta G` is also negative
