Explanation:
The Freundlich equation or Freundlich adsorption isotherm, an adsorption isotherm, is an empirical relation between the concentration of a solute on the surface of an adsorbent to the concentration of the solute in the liquid with which it is in contact.Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent. ... Adsorption is a surface phenomenon, while absorption involves the whole volume of the material.
Effect of pressure on the adsorbate gas
(i) An increase in the pressure of the adsorbate gas increases the extent of adsorption.
(ii) At low temperature, the extent of adsorption increases rapidly with pressure.
(iii) Small range of pressure, the extent of adsorption is found to be directly proportional to the pressure.
(iv) At high pressure (closer to the saturation vapour pressure of the gas), the adsorption tends to achieve a limiting value
