Name four factors affccting adsorption gases by solids.

Explanation

Factors affecting adsorption of gases by solids are:
(i) Nature of Adsorbent A gas is adsorbed in different amounts an different adsorbents.
(ii) Surface area Increase in the surface area of the adsorbent, increases the total amount of the gas adsorbed because number of adsorbing sites increases
(iii) Effect of Temperature Adoption is an exothermic process, thus favours lower temperature.
(iv) Pressure Increase in pressure at given temperature, increases adsorption of gas.
