ESTIMATION OF STEADY STATES NUMBER OF ONE-ROUTE CATALYTIC REACTIONS

Abstract

For one-route catalytic reactions the relationship between the number of reversible steps and the number of internal steady states (ISS) is investigated. For reactions having trimolecular steps, among which there is only one reversible stage, the number ISS increases to infinity together with the increase of the number of intermediate substances. The model of a reaction with 2n intermediate substances for which the ISS number is equal to n-1 is described. If there are no limitations in the number of reversible steps in a reaction mechanism, then the number of ISS grows exponentially together with the growth of number of intermediate substances. The model of a bimolecular homogeous reaction (a reaction whose steps have similar molecularity) with 3n intermediate substances is given. It can have 2n ISS.
