Why Freundlich adsorption isotherms fails at high pressure conditions?
We can take the value of n as 1.
Moreover the value of n lies between 0 and 1.
So according to Freundlich for high pressure conditions n is always taken as 1. And hence x/m=1
But experimentally it was found that saturation still increases even after increasing the pressure.
This is how Freundlich equation fails at higher pressure

There is a saturation level for the adsorption of any adsorbate on the adsorbent due to limited surface area of the adsorbent. So once that saturation level is reached , more pressure won't increase the number of particles adsorbed .
