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 strength of van der Waals' forces

Text Solution

Verified by Experts

The correct Answer is:
B
Extent of physisorption of a gas increases with decreases in temperature. Because in physisorption particles are held to the surface by weak van der Waal.s force of attraction hence on increasing temperature they get desorbed easily.
