Statement - I : A gas with higher critical temperature is adsorbed more than a gas with lower critical temperature
Statement - II : At higher temperature the gas with higher T_c is more easily liquefiable

Thus, a gas with higher critical temperature gets adsorbed to more extent than a gas with lower critical temperature.
Easily liquifiable gases have higher critical temperature and stronger van der Waal's forces of attraction.
Thus easily liquifiable gases get adsorbed to more extent.
For example, easily liquefiable gases like SO₂​,NH₃​,HCl,CO₂​ etc are readily adsorbed than gases which do not liquify easily. Such gases include H₂​,O₂​,N₂​.
