Abstract
In a Ferroin-catalyzed oscillatory Belousov-Zhabotinskii reaction, the temperature dependences of the largest Lyapunov exponent (LLE) and the induction period for a chaotic regime to appear are linear in the 285–308 interval when plotted on Arrhenius coordinates. For the LLE, the activation energies calculated for different concentrations of the catalyst are in the 82–126 kJ/mole interval, and for the induction period in the 61–95 kJ/mole interval. On the basis of the experimental data, it has been concluded that this autooscillatory chemical system, within a narrow range of catalyst concentrations, is relatively insensitive to random, small, external perturbations.
