Extent of physisorption of a gas increases with ………. .

A

increase in temperature.

B

decrease in temperature.

C

decrease in surface area of adsorbent.

D

decrease in strengyh of van der Walls' forces.

Text Solution

Verified by Experts

The correct Answer is:
B
Increase in temperature leads to desorption. Therefore, extent of physisorption decreases. Therefore, extent of physisorption of a gas increases with decrease in temperature.
