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 .
