Vedclass · Answer

(B) $1$. Physisorption is caused by weak van der Waals forces and is reversible in nature. $2$. Chemisorption involves strong chemical bonds and is irreversible. $3$. Physisorption is multi-layered,whereas chemisorption is unimolecular (forms a single layer). $4$. The enthalpy of adsorption for chemisorption $(80-240 \ kJ \ mol^{-1})$ is much higher than that for physisorption $(20-40 \ kJ \ mol^{-1})$. $5$. Therefore,the statement that chemisorption forms multimolecular layers is incorrect.
