How do size of particles of adsorbent, pressure of gas and prevailing temperature influence the extent of adsorption of a gas on a solid?

Solution

The extent of adsorption of gases on a solid surface depend on following factor:

Surface area of adsorbent: The extent of adsorption increases with the increase of surface area of the adsorbent. Thus, finely divided metals and porous substances having large surface areas are good adsorbents.

It depends on the nature of gas. More easily liquefiable gases are adsorbed readily.

Low temperature is favourable for adsorption. It decreases with increase of temperature
