Most commercial adsorbents rely on physical adsorption; while catalysis relies on chemisorption. ... Physical adsorption will occur under suitable temperature-pressure conditions in any gas solid system, while chemisorption takes place only if the gas is capable of forming a chemical bond with the surface .....jai hind...

Answer:
Adsorption isotherm is the variation of the mass of the gas (adsorbate) adsorbed per gram of the adsorbent with pressure at constant temperature.
The Freundlich adsorption isotherm is the mathematical representation for the variation of the extent of adsorption (x/m) with pressure (P) at a given temperature. Here, x is the mass of adsorbate and m is the mass of adsorbent.
The expression is
m
x
=k×P
n
