Vedclass · Answer

(D) $ 	ext{Physisorption} $ is an exothermic process,meaning the enthalpy of adsorption $( \Delta H_{	ext{adsorption}} )$ is negative $( -Ve )$.It involves weak $ 	ext{van der Waals} $ forces,resulting in a low enthalpy change,typically in the range of $ 20-40 \ kJ \ mol^{-1} $.Since it is an exothermic process,the correct statement is that $ \Delta H_{	ext{adsorption}} $ is low and negative $( -Ve )$,making option $ D $ the incorrect statement.
