While reading surface chemistry, I got
Rate of adsorption is high at begining and then decreases till equilibrium is attained . On the other hand , rate of absorption remains same throughout the process .
Regarding adsorption I have no doubts as logically after some time there will be no surface area for upcoming molecules. But how the rate can be same in case of absorption ? Just if we take an example of cotton ball , it absorbs water and after some time being fully wet by water how further the rate of absorbing be same ? Please help if I am lacking somewhere in the concept ...
