WebSep 14, 2024 · In chemisorption, the forces that are involved are very strong such as ionic bonds, covalent bonds, and certain types of intermolecular forces. Chemisorption is also known as activated adsorption. This type of adsorption is highly selective such that, only certain types of gas molecules are adsorbed by specific types of solids. Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate (solute )* on the surface of the adsorbent(solvent). This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or solid (the absorbent).
