Abstract: The limits of validity of the phenomenological rate equation, and the phenomenological rate constant kf and kb are found for the exchange reaction A + BC AB + C within the framework of simple multistate models. The possibility of macroscopically long transient times is discussed. The rate constants are shown to depend on the total densities nA, nB and nC of the chemical species present in the mixture, when nonequilibrium effects are important. The distinction between a rate constant and a flux coefficient is illustrated. Differences among exchange, dissociation-recombination, and isomerization reactions in that regard are discussed.
