✦ Synopsis

The chaotic behavior produced by a reaction system composed of consecutive quadratic and cubic autocatalytic elementary steps has been described. It is shown that the existence of chaotic behavior does not depend on the presence of a reaction step involving cubic autocatalysis because chaotic behavior is preserved when the cubic step is replaced by successive bimolecular steps involving an intermediate_ The chaotic behavior, as characterized by the Lyapunov exponents, displayed by the model based on the bimolecular approximation approaches, in the limit, that of the model based on cubic autocatalysis. Chaos also occurs for the bimolecular aDDroximation model for situations in which the limiting situation of cubic autocatalysis is not approached.--
