Question

define physical and chemical adsorption with suitable example?

Answer 1

chemistry, absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter some bulk phase – liquid or solid material. ...
The process of absorption means that a substance captures and transforms energy.

Answer 2

Physisorption, also called physical adsorption, is a process in which the electronic structure of the atom or molecule is barely perturbed upon adsorption.

Chemisorption is a kind of adsorption which involves a chemicalreaction between the surface and the adsorbate. New chemicalbonds are generated at the adsorbant surface. Examples include macroscopic phenomena that can be very obvious, like corrosion, and subtler effects associated with heterogeneous catalysis.
