Abstract
The original Oregonator model to the Belousov–Zhabotinsky oscillating reaction used three composition variables, five rate constants, and one stoichiometric factor involving five irreversible reaction steps. As a result of objections to the stoichiometric factor by Noszticzius, Farkas, and Schelly, we have developed an alternative model of the same complexity based on six irreversible steps. The revised model eliminates some stoichiometric difficulties, and by minor modification of one of the six steps it handles situations in which the final oxidation state of the reduced bromine is +1, 0, or −1. An alternative skeleton model called the Explodator and proposed by Noszticzius, Farkas, and Schelly should not be considered a viable alternative to the Oregonator unless a computational prerequisite and an experimental kinetic prerequisite can both be satisfied.
