Answer
Adsorption isotherm is the variation of the mass of the gas (adsorbate) adsorbed per gram of the adsorbent with pressure at constant temperature.
Freundlich adsorption isotherm:
Freundlich adsorption isothermic given an empirical relationship between the quantity of gas adsorption by the unit mass of solid adsorbent and pressure at a specific temperature.
From the given plot it is clear that at pressure
P
s ,
s ,
(x)/(M) reaches the maximum values Ps is called the saturation pressure.
K and n are constants for a given adsorbate and adsorbent at a particular temperature.
At high pressure 1/n = 0, hence extent of adsorption becomes independent of pressure.
