The adsorption of a gas on a solid surface varies with
pressure of the gas in the following manner :
Fast → slow → independent of the pressure
- In the beginning, the rate of adsorption of the gas on any solid surface is fast on applying pressure
-after some time, the rate gets slower
- and after a certain time, the rate of adsorption becomes independent of the pressure
- so the correct option is (a)
