Dynamics of Two-Stage Catalytic Reactions with Marcelin-de Donde Kinetics in an Open System

The dynamics of chemical reactions depends on the kinetic law (KL) and is characterized by relaxation times, making it possible to determine the speed and duration of their implementation. M.I. Temkin analyzed the relaxation time of the simplest two-stage catalytic reaction proceeding quasi-stationary in an open isothermical system according to the ideal law of mass action. This article examines the features of the relaxation processes of two-stage catalytic reactions, proceeding according to the nonideal kinetic Marcelin-De Donde (MDD) law, which relates reaction rates to the chemical potentials of the regents.
