Chemical adsorption, also known as chemisorption, solid materials is achieved by substantial sharing of electrons between the surface of adsorbent and adsorbate to create a covalent or ionic bond. Thus, chemical adsorption may not be fully reversible and could require high energy for regeneration.

Chemisorption is the type of adsorption in which adsorbate bind with adsorbent by strong chemical bonding like covalent etc, so it is very tough to break those type of bonding thus is irreversible phenomenon.

Deadsorption is simultaneous in such cases, It is not always irreversible trend.

In chemisorption, Heat is also needed Why not B?
