New chemical bonds are generated at the adsorbent surface. Chemisorption plays a crucial role in catalysis because it facilitates the activation of reactant molecules Chemisorption is defined as the process involving the formation of strong chemical bonds between specific functional groups on an adsorbent surface and contaminants, resulting in an irreversible adsorption complex that requires higher energy input compared to physisorption.

Physisorption and chemisorption are two fundamental mechanisms by which gases interact with solid surfaces
Both play crucial roles in various industrial and scientific processes, including catalysis, filtration, and material synthesis.
Chemisorption is the process in which the adsorbate particle, as well as the adsorbent particles, are adhered to each other by the means of a chemical bond between them. Chemisorption plays an indispensable role in catalysis and surface reactions, fundamentally transforming various chemical processes by facilitating reactant interactions at an atomic level. In reality, of course, such a mechanism for dissociative hydrogen chemisorption is not practical Instead, a hydrogen molecule will initially approach the surface along the physisorption curve.
Often chemisorption produces reaction products which are swept out of the sample cell to the detector In such cases, to prevent obscuring the adsorption signal, it is necessary to remove the reaction products from the flow stream. Chemisorption, or chemical adsorption, is a surface phenomenon where a chemical reaction occurs between the adsorbate (gas or vapor) and the exposed surface of a solid material.
