Which one of the following characteristics is with adsorption?

A

`DeltaGandDeltaS` are negative but `DeltaH` is positive

B

`DeltaG` is negative but `DeltaHandDeltaS` are positive

C

`DeltaG,DeltaHandDeltaS` all are negative

D

`DeltaGandDeltaH` are negative but `DeltaS` is positive

Text Solution

Verified by Experts

The correct Answer is:
C
Adsorption is a phenomena where entropy decrease enthalpy also decreases `(DeltaHlt0)`
As per Gibbs Helmholtz equation `DeltaG=DeltaH-TDeltaS`
At spontaneous adsorption:
`DeltaSlt0,DeltaGlt0 & DeltaHlt0`
