Why does physisorption 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.

The correct statement(s) pertaining to the adsorption of a gas on a solid surface is(are) (i) adsorption is always exothermic (ii) physisorption may transform into chemsisorption transform into chemisorption at high temperature (iii) physisorption increases with increasing temperature but chemisorption decreases with increasing temperature .
