Question

give two examples of chemisorption

Answer 1

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 adsorbate and the substrate surface creates new types of electronic bonds.

hope it helped!!

Answer 2

The chemical bonds may be covalent or ionic in nature. Examplesinclude adsorption of nitrogen or hydrogen on the surface of Fe catalyst. The adsorption of hydrogen on the surface of Ni catalyst is an example of both physisorption andchemisorption....
