what are the factors affecting absorb of gas and solids
Answers
Answer:
Factors affecting adsorption of Gases by Solids
Nature and Surface area of adsorbent:
The same gas is adsorbed by different solids at different extents even at the same temperature.
Greater the surface area, greater is the volume of gases adsorbed.
Nature of the gas being adsorbed:
Different gases are adsorbed are adsorbed to different extents even by the same solid.
As the critical temperature of a gas increases, it is easier to liquefy and it is also more readily adsorbed.
Reason- Higher the critical temperature, the easier it is to liquefy the gas as greater are the intermolecular forces to attraction between the molecules of the gas. For such a gas, the intermolecular forces of attraction are greater on the surface of the adsorbent and thus, the adsorption will be more.
Explanation:
When a solid surface is brought in contact with a gas or liquid, molecules from the gas or liquid starts to collect at the surface of the solid. This phenomenon of a collection of gas or liquid molecules on the surface of the solid is known as adsorption. A substance which accumulates on the solid surface is known as adsorbate and the solid surface on which it occurs is known as an adsorbent.
