Question

how is the adsorption of gas related to it critical temperature​

Answer 1

Answer:

Solution : Higher the critical temperature of a gas, greater the ease of liquefication, i.e., greater the van der Waals forces of attraction and hence greater the adsorption.

Answer 2

Answer:

Higher is the critical temperature of a gas, greater is the ease of liquefication, i.e., greater are the van der Waals' forces of attraction and hence greater is the adsorption

Explanation:

adsorption is the play of intermolecular attractions between adsorbent and adsorbate (which gets adsorbed). Critical temperature is the temperature above which we can not liquify gas just by pressure alone. So beyond critical temperature, there will be negligible intermolecular attractions between the gas molecules.
