Chemisorption said to be irreversible but the graph between temperature and chemisorption decrease after the activation energy indicating desorption? Why?

Q. Assertion :In chemisorption, adsorption keeps on increasing with temperature. Reason: Heat keeps on providing more and more activation energy.

Q. Assertion :In chemisorption, adsorption first increases with temperature and then decreases. Reason: Heat keeps on providing more and more activation energy.

Q. The correct statement(s) pertaining to the adsorption of a gas on a solid surface is(are):
(i) adsorption is always exothermic.

(ii) physisorption may transform into chemisorption at high temperature.
(iii) physisorption increases with increasing temperature but chemisorption decreases with increasing temperature.
(iv) chemisorption is more exothermic than physisorption, however, it is very slow due to the higher energy of activation.

Q. Statement: Physical adsorption is weaker than chemical adsorption.
Explanation: Activated complex formed during adsorption possess lower energy level in chemisorption as it is more exothermic.
