Question

Discuss the difference between physisorption and chemisorption

Answer 1

Explanation:

In this type of adsorption, the adsorbateis attached to the surface of the adsorbent with weak van der Waal's forces of attraction. In this type of adsorption, strong chemical bonds are formed between the adsorbate and the surface of the adsorbent.

Answer 2

HEYA MATE HERE YOU GO

PHYSISORPTION :-

➡ It arises because of van der waal's forces.

➡It is not specific in nature.

➡It is reversible in nature.

➡It depends on the nature of gas easily liquefiable gases are adsorbed readily.

➡Enthalpy of adsorption is low (20-40 KJ mol-1).

CHEMISORPTION :-

➡It is caused by chemical bond formation.

➡It is highly specific in nature.

➡It is irreversible.

➡It also depends on the nature of gas gases which can react with the adsorbent show chemisorption.

➡Enthalpy of adsorption is high (80-240 KJ mol-1).
