**Gibbs Isotherm**

The **Gibbs adsorption isotherm for multicomponent systems** is an equation used to relate the changes in concentration of a component in contact with a surface with changes in the surface tension. For a binary system containing two components, the Gibbs adsorption equation in terms of surface excess is:

where

- is the surface tension,
_{1}is the surface excess of component 1,_{1}is the chemical potential of component 1.
