Question

Why is chemisorption referred to as activated adsorption?

Open in App

Solution

In chemisorption, a true chemical bond formation occurs between reactant and adsorbent molecules.

We know, high activation energy is required for chemical bond formation, which requires high temperature.

Therefore, chemisorption is known as activated adsorption

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.

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

Q. A physical adsorption at low temperature may pass into chemisorption as:
