Adsorption isotherms of mobile monolayers

In such a case, the solution analogy is perfect. Hill s model can therefore be applied here. The equation for the isotherm is as previously stated, that is to say  

In fact, this model does not take into consideration the interaction between adsorbed molecules. However, the trath is that, generally, the hypothesis of a dilute solution cannot be used when studying adsorption phenomena therefore, the thermodynamic model for solutions will rarely be of any help to us.
