Gibbs adsorption isotherm
« on: October 28, 2020, 05:28:07 PM »
My lecture notes say:

If ηi is the amount of component I in the surface phase σ in excess of that which would have been in
σ had the bulk phases α and β extended to a surface S with unchanging composition then the surface
excess concentration of solute Γι of component I is given by:

Γι = ηi / A

Does anyone know what he is trying to say?
