It is shown that in multiple-equilibrium systems the reaction extents are uniquely determined only if all the equilibria considered are stoichiometrically independent. Otherwise numerical values for reaction extents, satisfying the mass-balance conditions, can be chosen in infinitely many ways. Irrespective of this, every reaction affinity (the derivative of the Gibbs energy with respect to the extent of the corresponding reaction) is independent of the particular (and arbitrary) choice of the reaction extent. These results corroborate the validity of the recently elaborated response-reaction-approach to chemical thermodynamics.
