Only the surface atoms in an adsorbent play an active role in adsorption. These atoms possess some residual force such as van der Waals forces and chemical forces. In the process of adsorption. Weak adsorbate is substituting by strong adsorbete. Activated charcoal used in the gas mask is already exposed to the atmospheric air, so gases and water vapours in air are adsorbed on its surface. When the mask is exposed to chlorine atmosphere, the gases are displaced by chlorine. In general, easily liquefiable gases such as CO_(2),NH_(3),Cl_(2), and SO_(2) are adsorbed to a greater extent than the elemental gases, e.g., H_(2),N_(2),O_(2), He, etc. Gas mask works on the principle of

Assertion: A gas with higher critical temperature gets adsorbed to more extent than a gas with lower critical temperature. Reason: The easily liquefiable gases get adsorbed to more extent which have higher critical temperature.

H_(2) gas is adsorbed on activated charcoal to a very little extent in comparison to easily liquefiable gases due to ……. .
