Which of the following is not a favourable condition for physical adsorption?

A

High pressure

B

Negative `DeltaH`

C

Higher critical temperature of adsorbate

D

High temperate

Text Solution

Verified by Experts

The correct Answer is:
D
Physisorption is a process in which adsorbate get adsorbed on the adsorbent surface by weak van der Waals’ force of attraction. On increasing temperature the interaction between adsorbate and adsorbent becomes weak and adsorbate particles get desorbed.
