摘要

化学反应的动力学取决于动力学定律（KL），并以弛豫时间为特征，从而可以确定其实施的速度和持续时间。M.I. Temkin根据理想质量作用定律，分析了开放等温体系中最简单的两级催化反应进行准稳态过程的弛缓时间。本文根据非理想动力学Marcelin-De - Donde （MDD）定律研究了两级催化反应弛豫过程的特征，该定律将反应速率与试剂的化学势联系起来。

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.
