Chemisorption is a kind of adsorption which involves a chemical reaction between the surface and the adsorbate. New chemical bonds are generated at the adsorbent surface. Examples include macroscopic phenomena that can be very obvious, like corrosion [clarification needed], and subtler effects associated with heterogeneous catalysis, where the catalyst and reactants are in different pha

English: This diagram depicts the process and benefits of sewage treatment. Sewage treatment helps to protect the environment and all organisms as this process aims to remove contaminants such as bacteria, nutrients, pathogens and any other chemicals that may contaminate surface waters.
A hydrologic model is a simplification of a real-world system (e.g., surface water, soil water, wetland, groundwater, estuary) that aids in understanding, predicting, and managing water resources. Both the flow and quality of water are commonly studied using hydrologic models.
Chemisorption often involves an activation energy. For physisorption gas phase molecules, adsorbates, form multilayer adsorption unless physical barriers, such as porosity, interfere. In chemisorption, molecules are adsorbed on the surface by valence bonds and only form monolayer adsorption.
The oxidation of hydrocarbons to water and carbon dioxide: 2 C 6 H 6 + 15 O 2 → 12 CO 2 + 6 H 2 O; This process can occur with any of hydrocarbon, but most commonly is performed with petrol or diesel. Asymmetric heterogeneous catalysis facilitates the production of pure enantiomer compounds using chiral heterogeneous catalysts. [26]

BET model of multilayer adsorption, that is, a random distribution of sites covered by one, two, three, etc., adsorbate molecules. The concept of the theory is an extension of the Langmuir theory, which is a theory for monolayer molecular adsorption, to multilayer adsorption with the following hypotheses:
