The rate of physisorption increases with

A

Decrease in temperature

B

Increase in temperature

C

decrease in pressure

D

Decrease in surface area

Text Solution

Verified by Experts

The correct Answer is:
A


Physical adsorption decreases with increase in temperature and vice versa at constant pressure. Physical adsorption is exothermic and it is favoured by a low temperature according to Le-Chatelier's principle.
