Why is the extent of chemisorption low at a lower temperature?

Text Solution

Verified by Experts

Chemical adsorption involves the formation of bonds between the adsorbate molecules and the particles on the surface of the adsorbent. This requires high activation energy. As a result, the extent of chemisorption becomes low at a lower temperature.
