Chemosorption is a term used to describe the process of a substance absorbing another through chemical reactions. Synonyms for this word include chemisorption, chemical adsorption, and surface reaction. Chemisorption involves the formation of strong covalent bonds between the adsorbent and the adsorbate molecule, while chemical adsorption involves weaker van der Waals forces. Surface reaction refers specifically to the reactions that occur at the surface of a solid material. All of these terms are used in chemistry to describe the same general process of a substance absorbing other substances through chemical interactions. The exact term used may depend on the specific context and level of technicality needed.
