Irreversible nature of adsorption

Vedclass · Answer

(B) The characteristics of physical adsorption $(Physisorption)$ are: $1$. It is not specific in nature. $2$. It is a reversible process. $3$. It results in multimolecular adsorption layers. $4$. It depends on the nature of the gas; more easily liquefiable gases are adsorbed readily. $5$. The enthalpy of adsorption is low $(20-40 \ kJ \ mol^{-1})$. $6$. Low temperature is favorable for adsorption,meaning adsorption decreases with an increase in temperature. $7$. There is no requirement for activation energy. $8$. It depends on the surface area; hence,porous surfaces are good adsorbents. Therefore,the statement that physical adsorption is irreversible is incorrect.
