In a series of papers (ref. 1-13) we have recently elaborated the concept of "response reactions", in order to interpret and rationalize the changes taking place in multiple-equilibrium systems, when the control parameters (pressure, temperature, initial amounts of substances) are altered. The concept helps to interpret certain unusual phenomena - frequently encountered in multiple-equilibrium systems - by decomposing the sensitivity coefficients in a linear way into terms uniquely assigned to response reactions. It has also been shown that the "configurational" or "relaxational" part of many important first derivatives in chemical thermodynamics may be expressed as a sum of terms, assigned to response reactions. The concept of response reactions opens a new way to formulate the change of the thermodynamic potential functions in terms of affinities. As a result, coupling between reactions appears in a natural and straightforward manner. The equations derived may be extended into the domain of irreversible thermodynamics.
