Original Abstract
Two published experimental confirmations of either the linear relationship between the reaction rate and its affinity or the "thermodynamic coupling" are revised. It is shown that "proved" results are more consequences of a given experimental arrangement or of methods used for the treatment of experimental concentration data than outcomes of some general thermodynamic law. The affinity should be considered not as a quantity determining the value of the reaction rate but as an alternative quantity for description of the evolution of a reacting system, its distance from equilibrium. The affinity perhaps expresses some potential for a reaction but its manifestation in the reaction rate is controlled by the very kinetics.
