✦ Synopsis

By using only well-defined measurable thermodynamic quantities, the entropy production by heat, mass and charge transfer in a discontinuous and a continuous system is derived. The derivation follows the principle that thermodynamic derivations should in general he carried out as far as possible without the introduction of any kind of model concerning structural units (ions)[ l-31. This is in contrast to the conventional thermodynamic treatment ofelectrolytes. The present description has fluxes and forces that depend on the choice ofelectrodes. lt is, however, shown that the local dissipated energy does not have this dependency. The components of the system are in accordance with the Gibbs phase rule. Corrections in electric forces due to the use of different electrodes at different temuerature or uressure are discussed. Chemical reactions with zero affinity are transport and a chemical reaction is discussed. treated, and the complete coupling between mass
