Chemisorption is a kind of adsorption which involves a chemical reaction between the surface and the adsorbate. New chemical bonds are generated at the adsorbant surface. Examples include macroscopic phenomena that can be very obvious, like corrosion, and subtler effects associated with heterogeneous catalysis. The strong interaction between the a...
(from the article `adsorption`) Adsorption can be either physical or chemical in nature. Physical adsorption resembles the condensation of gases to liquids and depends on the ... ...of a particular component may prefer one environment over the other. If the molecules of one component in the solution prefer to be at the ... [2 related...
The binding of an adsorbate to the surface of a solid by forces whose energy levels approximate those of a chemical bond. Contrast with physisorption.

[n] - adsorption (especially when irreversible) by means of chemical instead of physical forces
chemosorption noun adsorption (especially when irreversible) by means of chemical instead of physical forces; `chemisorption of gaseous nitrogen on iron catalysts`
Attachment, by chemical means, of a single layer of molecules, atoms, or ions of gas to the surface of a solid or, less frequently, a liquid. It is the basis of some types of catalysis (see catalyst) and is of great industrial importance
adsorption involving a chemical linkage between the adsorbent and the adsorbate.
