Abstract

A large class of first partial derivatives involving the eight common thermodynamic variables (P, V, T, U, H, S, F, G) in systems with multiple chemical equilibria is known to be decomposable into two components, referred to as "non-chemical" and "chemical". We examine the chemical component and its dependence on the various equilibria occurring in the system considered. It is shown that the chemical component may be expressed in terms of response reactions which were previously introduced in the study of sensitivity coefficients in equilibria achieved under T, P = const. Details of our analysis are given for only one partial derivative, namely for the Joule-Thomson coefficient, pertaining to chemical equilibria under adiabatic conditions H, P = const.
