Why do physisorption and chemisorption behave differently with rise in temperature?

Text Solution

Verified by Experts

Behaviour of physisorption and chemisorption on increase in temperature can be explained on the basis of nature of forces present to bind their particles. Physisorption involves weak van der Waal.s forces which weakens with increase in temperature. Chemisorption involves formation of chemical bond, which requires activation energy hence, it is favoured by rise in temperature.
