The correct statement(s) 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
Adsorption is exothermic at high temp physisorption transfer to chemical adsorption `DetlaH` is more for chemisorption [40 - 400]
  Activation energy in more
