Freundlich proposed the following empirical equation for adsorption of a gas on solid.
\(\frac{x}{m}\) = k P1/n (n > 1) ……(i)
Where,
x = Mass of the gas adsorbed
m = Mass of the adsorbent
\(\frac{x}{m}\) = Mass of gas adsorbed per unit mass of adsorbent
P = Equilibrium pressure k and n are constants which depend on the nature of adsorbate, adsorbent and temperature.
