| Sumario: | The Bray-Liebhafsky reaction exhibits different nonlinear behaviors during the iodate catalyzed decomposition of acidic hydrogen peroxide in the different conditions. Both the chaotic and regular oscillations were observed. The largest Lyapunov exponent (λL), the power spectram and the log(P)-log(f) dependence for power spectram were used to evalúate these nonlinear behaviors. The effect of initial concentration of reactants on the types of oscillations and the initial potential (E o) were discussed in detail. The possible mechanism of the Bray-Liebhafsky reaction was also approached in this work |
