Answer to Question #98754 in Physical Chemistry for Abhishek

Question

Distinguish between physisorption and chemisorption .

Answer 1

Solution.

If the interaction between the adsorbent and the adsorbate is limited to intermolecular interaction and is a manifestation of physical forces (for example, induction or electrostatic interaction), then it is physisorption.

If the interaction between the adsorbent and the adsorbate manifests itself in the form of chemical forces (redistribution of electron density, chemical reaction), it is chemisorption.

Answer:

If the interaction between the adsorbent and the adsorbate is limited to intermolecular interaction and is a manifestation of physical forces (for example, induction or electrostatic interaction), then it is physosorption.

If the interaction between the adsorbent and the adsorbate manifests itself in the form of chemical forces (redistribution of electron density, chemical reaction), it is chemisorption.
