The correct statement(s) pertaining to the adsorption of a gas on a solid surface is/are :

A

Adsorption is always exothermic

B

Physisorption may transform into chemisorption at high temperature

C

Physisorption increases with increasing temperature but chemisorption decreases with increasing temperature

D

Chemisorption is more exothermic than physisorption, however it is very slow due to higher energy of activation.

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
(A) `triangle H = -ve` for adsorption
(B) fact
(D) chemical bonds are stronger than vander waal's forces so chemical adsorption is more exothermic.
