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

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

The rate of physisorption increases with

Rate of physisorption increases with :

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

The extent of adsorption of a gas depends upon the

Assertion: In physisorption, adsorption increase with increases in temperature. Reason: Physisorpation is of exothermic nature.
