A stochastic model of chemical equilibrium in a system where the two-stage consecutive reversible first-order reaction takes place

摘要

For a reversible two-stage consecutive first-order chemical reaction taking place in as closed system the equilibrium fluctuations of the composition are characterized by a stationary distribution of states in the macroscopic chemical equilibrium,the distribution and the mean value of the length of fluctuations about the state of exact chemical equilibrium, the mean lifetime of this state and the frequency of visits of theis state.Some features of concentration fluctuations of the reaction intermediate are analyzed.An amplitude and a region of equilibrium fluctuations are defied.The results generalize those obtained for a one-stage reversible first-order reaction.
