Lagmuir derived the expression given below:
The values of constants “a” and “b” depends upon the nature of adsorbate, nature of solid adsorbent, and temperature. “p” is equilibrium pressure
Lagmuir theory has limitations. This theory of unimolecular adsorption is valid only at low pressure and high temperature.
As the pressure is increases or temperature is lowered, additional layer starts forming . This leads to multilayer adsorption.
