Question

Why easily liquefiable gases are adsorbed more readily?

Answer 1

The amount of gas adsorbed by a solid depends on the nature of gas. In general easily liquefiable gases (i.e. with higher critical temperature) are readily adsorbed. Thus of activated charcoal adsorbs moresulfur dioxide (critical temperature ) than methane (critical temperature ).

Answer 2

The extent of adsorption depends upon the nature of the gas.The gad which are more readily adsorbed than others .For e.g.under similar conditions, the amount of So2 or NH3 adsorbed by charcoal is much more than that of H2 or O2 gases.It is because, the intermolecular forces are stronger in more easily liquifiable gases, therefore they get adsorbed more strongly
