Write an equation for Freundlich adsorption isotherm.

1.	Write an equation for Freundlich adsorption isotherm.
Answer» Freundlich proposed the following empirical equation for adsorption of a gas on solid. \(\frac{x}{m}\) = k P^1/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.

Answer»

Freundlich proposed the following empirical equation for adsorption of a gas on solid.

\(\frac{x}{m}\) = k P^1/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.
