Why dows physisoption decrease with increase of temperature ?

Text Solution

Verified by Experts

Physisorption is an exothermic process `:`
`underset((Adso rbent))(Soli d)+underset((Adso rbate))(Gas)hArrunderset((Gas adso rbed on sol i d))(Gas//Soli d)+Heat`
According to Le`-` Chatelier's principle, if we increase the tmeperature, equilibrium will shift in the backward direction,` i.e.,` gas is released from the adsorbed surface.
