Chemisorption

Chemisorption is a process where molecules or atoms form a strong, often covalent, bond with a surface, such as a metal or catalyst. Unlike physical adsorption, which involves weak forces, chemisorption results in a more permanent attachment, typically involving electron sharing or transfer. This process is essential in many chemical reactions, like catalysis, because it activates the molecules, making it easier for them to undergo transformation. Overall, chemisorption is a surface phenomenon characterized by the formation of chemical bonds, significantly influencing reaction rates and mechanisms.
