Vedclass · Answer

(C) Physical adsorption (physisorption) is characterized by weak van der Waals forces between the adsorbate and the adsorbent. $1$. It is a reversible process. $2$. It involves low enthalpy of adsorption (usually $20-40 \ kJ \ mol^{-1}$). $3$. It does not require high activation energy because the forces involved are weak. $4$. It is favored at low temperatures and decreases with an increase in temperature. Therefore,the statement that it requires high activation energy is incorrect.
