Abstract

The long-time properties of a system with initially separated components and two competing reactions, reversible [formula presented] and irreversible [formula presented] are studied. It is assumed that the backward constant [formula presented] of the reversible reaction [formula presented] is small. The dynamics of the system is described by means of a crossover from an “irreversible” regime (for times [formula presented] to a “reversible” regime (for times [formula presented] It is shown that in contrast to the “irreversible” regime, where both reactions occur in one reaction zone, the “reversible” regime is characterized by two distinctive reaction zones. These are the [formula presented] reversible reaction zone and the [formula presented] irreversible reaction zone. Numerical computations of the mean-field kinetic equations confirm these asymptotic results.
