Adsorption of a gas follows freundlich adosorbed isotherm. x is the mass of the gas adsorbed on mass m of the adsorbent. The plot log $$x \over m$$ versus log p is shown in the given graph. $$x \over m$$ is proportional to :

Among the following the false statement is -

Given

Gas	H2	CH4	CO2	SO2
Critical Temperature / K	33	190	304	630

On the basis of data given above, predict which of the following gases shows least adsorption on a definite amount of charcoal ?
