Vedclass · Answer

(C) Physical adsorption (physisorption) is an exothermic process. According to Le Chatelier's principle,for an exothermic process,the extent of adsorption decreases with an increase in temperature. Therefore,the statement that physical adsorption increases with an increase in temperature is incorrect. Physisorption is non-specific,involves low enthalpy of adsorption (usually $20-40 \ kJ \ mol^{-1}$),and typically forms multilayer adsorption.
