| Abstract Scope |
The entropy production of irreversible processes such as diffusion, heat flow or molecular reactions plays a major role in the kinetics of the processes. The driving forces are derived from the entropy production and when combined with kinetic properties they allow a mathematical description of the processes.
Hillert (1) applied Gibbs’ well-known equation for a multicomponent system but added the entropy-production term which he obtained by combining the first and second law for a general non-equilibrium process. This important modi-fication allows a general treatment which many researchers are not aware of. The aim of the presentation is to give an overview of Hillert’s approach and some examples.
