Thermodynamics of Interfaces

This lecture covers the fundamental concepts of interfacial chemistry, focusing on the thermodynamics of interfaces. Topics include the Gibbs dividing plane, relative absorption of solutes, surface excess quantities, and the derivation of the Gibbs adsorption isotherm. The lecture also discusses the location of the dividing plane in the Gibbs Model, interfacial excess number of moles, and measurements of interfacial adsorption. Furthermore, it explores the role of surfactants, micelle formation, and the impact of surfactant concentration on surface tension.
