Which of the following is incorrect for physisorption?

Question

Which of the following is incorrect for physisorption? (A) Reversible (B) Increases with increase in temperature. (C) Low heat of adsorption. (D) Increases with increase in surface area

Tardigrade Admin · Accepted Answer

Since, the adsorption process is exothermic, the physical adsorption occurs readily at low temperature and decreases with increase in temperature (Le-Chatelier's principle).
