Which of the following gas is liberated, when sodium carbonate is reacted with Hydrochloric acid ?

Only the surface atoms in an adsorbent, play an active role in adsorption. These atoms posses some residual forces like vander Waal's forces and chemical forces. In the process of adsorption, weak adsorbate is substituted by strong adsorbate. Activated charcoal used in gas mask is already exposed to the atmospheric air, so the 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. Porous and finely powdered solids, e.g., charcoal and Fuller's earth adsorb more as compared to the hard non-porous material. It is due to this property that the powdered characoal is used in gas masks. In general, easily liquefiable gases like CO_2, NH_3, Cl_2 , and SO_2 etc., are adsorbed to a greater extent than the elemental gases, eg., H_2, N_2, O_2, He , etc. Which of the following gases will be most easily adsorbed by the charcoal in the gas mask
