Answer 2

Chemical adsorption, also known as chemisorption, on 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.
