Extent of physisorption of a gas increase 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

Rate of physisorption increases with decrease in temperature increase in temperature decrease in pressure decrease in surface area

Give reason for the Physisorption decreases with increase in temperature.

How does entropy changes with a. Increase in temperature b. Decrease in pressure?

Why dows physisoption decrease with increase of temperature ?

In the following question, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as. Assertion (A): Extent of physisorption of a gas increases with decrease in temperature. Reason (R): It is due to decrease in strength of van der Waals forces.
