Question

Why easily liquefiable gases are adsorbed more readily?

Answer 1

The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than aliquid or solid

Answer 2

Answer:

The phenomenon of adsorption of gases by solids depends upon the following:

Nature of adsorbent and adsorbate : The amount of the gas adsorbed depends upon the nature of the adsorbent and the gas (adsorbate) which is to be adsorbed. Gases like SO2, NH3, HCl and CO2 , which liquefy more easily are adsorbed more readily than the permanent gases like H2,N2 and O2 which do not liquefy easily.

This is because the easily liquefiable gases have greater van der waal's or the molecular forces of attraction or cohesive forces. As the critical temperatures of the easily liquefiable gases are more than the permanent gases, it follows that higher the critical temperature of the gas (adsorbate), the greater the extent of adsorption.
