Question

(C) Physical adsorption (physisorption) is a multilayered process due to weak van der Waals forces. Chemical adsorption (chemisorption) is irreversibl

Vedclass · Accepted Answer

On increasing the temperature physical adsorption first increases then decreases

Vedclass · Answer

(C) Physical adsorption (physisorption) is a multilayered process due to weak van der Waals forces. Chemical adsorption (chemisorption) is irreversible because it involves the formation of strong chemical bonds. For physical adsorption,the extent of adsorption decreases with an increase in temperature because it is an exothermic process. Therefore,the statement '$On \ increasing \ the \ temperature \ physical \ adsorption \ first \ increases \ then \ decreases$' is incorrect. Langmuir adsorption isotherm is generally used to describe chemisorption.
