Modeling of critical phenomena in a five-step reaction of the catalytic oxidation of carbon monoxide

We construct a model of the dynamics of the five-step catalytic reaction of the oxidation of carbon monoxide with the formation of an unreactive form of an intermediate substance (buffer step). We construct the line of multiplicity and the line of neutrality in the plane of the constants of the reaction rates. It is shown that the inclusion of the mechanism of reaction buffer stage affects the variety of dynamic modes.
