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).

HOPE THIS WILL HELP YOU .
