Factor Affecting Adsorption of Gases on Solids

Nature of the gases:

The easily liquefiable gases \left(\mathrm{HCl}, \mathrm{NH}_{3}, \mathrm{Cl}_{2}\right., $ etc $) are adsorbed more than the gases like \left(\mathrm{H}_{2}, \mathrm{~N}_{2}, \mathrm{O}_{2}\right.$,etc. $)

ature of adsorbent: Extent of adsorption is directly proportional to the surface area of solid. So, finely divided adsorbents are more efficient than normal one. Example:

Activated charcoal, clay etc. can adsorb gases which are easily liquified.

Gases such as \mathrm{H}_{2}, \mathrm{N}_{2} and \mathrm{O}_{2} are generally adsorbed on finely divided transition metals \mathrm{Ni} and \mathrm{Co}

To increase the adsorbing power of adsorbents. They are subdivided into smaller pieces thus increasing their surface area and hence the adsorbing power.
