A general differential kinetics equation for several kinds of reversible reactions is proposed. By combining this equation with dimensionless parameters, some math. models of reversible reaction kinetics are suggested, which are used for calculating both rate and equilibrium constants An application of the models is given and the results are in agreement with those in the literature. The math. models of first-order and second-order reaction kinetics are also derived as specific examples of the application of this approach.6
