Abstract: Many features and disadvantages of reaction mechanisms and models suggested for BR (Briggs-Rauscher) oscillatory system are summarized briefly in this paper. Moreover, a simplified model for a nine-step reaction mechanism is proposed which can simulate concentration variations of the following four species HIO2, I2, I- and O2.The model exhibits periodic oscillatory behavior in a wide range of initial concentrations of inflow species, and can be used to elucidate some special experimental phenomena. Additionally, limit cycle and bistabilty are observed in this model.

Key words: BR oscillatory reaction, Mechanism, Model, Limit cycle, Bistability
