Description
Summary:We report an effect of temperature and small amounts of metal ions on transient chaotic regime observed in the batch Belousov–Zhabotinsky oscillating chemical reaction catalyzed by ferroin. The transient chaos is quantified by values of the largest Lyapunov exponent and induction period. We have found that these values depend through the Arrhenius equation on the temperature if the initial ferroin concentration is varied in the range of (0.87–3.5)×10 −3 M . We show that inside this range transient chaos is characterized by linear response to injection of solutions containing metal ions, e.g., cerium(III), manganese(II), vanadyl(IV) or thallium(I).
