A large class of first partial derivatives involving the eight common
thermodynamic variables (P, V, T, U, H, S, F, G) in systems with multi
ple chemical equilibria is known to be decomposable into two component
s, referred to as ''non-chemical'' and ''chemical''. We examine the ch
emical component and its dependence on the various equilibria occurrin
g in the system considered. It is shown that the chemical component ma
y be expressed in terms of response reactions which were previously in
troduced in the study of sensitivity coefficients in equilibria achiev
ed under T, P = const. Details of our analysis are given for only one
partial derivative, namely for the Joule-Thomson coefficient, pertaini
ng to chemical equilibria under adiabatic conditions H, P = const.
