CHEMISORPTION Meaning and
Definition
-
Chemisorption is a type of adsorption process that involves a strong chemical bond formation between the surface of a solid material and the adsorbate molecules. It is a surface phenomenon where the adsorbate species undergo a chemical reaction with the adsorbent surface, leading to the formation of new chemical species.
In chemisorption, the adsorbate molecules are not merely physically attached to the surface; rather, they become chemically bound to the adsorbent through the sharing or transfer of electrons. This bond formation results in the formation of a new compound on the surface of the adsorbent.
Unlike the weaker physical adsorption (physisorption), chemisorption is characterized by a higher energy requirement due to the formation of new chemical bonds. It involves the breaking of existing bonds and the creation of new ones. Therefore, chemisorption is more specific and selective in nature, dependent on the nature of the adsorbate and the adsorbent.
Chemisorption plays a crucial role in various chemical processes, including catalysis and surface reactions. It can enhance the overall reaction rate, promote specific chemical transformations, or allow the adsorbed species to be in an activated state for subsequent reactions.
Understanding the mechanism and kinetics of chemisorption is vital in fields such as materials science, heterogeneous catalysis, and surface chemistry, as it has implications for the design and optimization of efficient catalysts and other applications involving surface reactions.

Etymology of CHEMISORPTION
The word "chemisorption" is derived from two terms: "chemi" and "adsorption".
The prefix "chemi" refers to chemistry or chemical, indicating a chemical aspect or process.
The term "adsorption" refers to the process by which molecules adhere to a solid surface. It is the opposite of absorption, where a substance is fully taken in and distributed throughout another substance. In adsorption, the molecules adhere to the surface through intermolecular forces such as van der Waals forces, electrostatic interactions, or even covalent bonds.
Combining these two terms, "chemisorption" refers to the process in which a chemical reaction occurs between the adsorbate (the substance being adsorbed) and the adsorbent (the solid surface).
