Vedclass · Answer

(C) Physisorption is an exothermic process because the formation of weak van der Waal's forces between the adsorbate and adsorbent releases energy. Therefore,the enthalpy of adsorption $(\Delta H_{adsorption})$ is always negative,typically ranging between $-20 	ext{ to } -40 	ext{ kJ/mol}$. Option $C$ states that the enthalpy is positive,which is incorrect.
