The dynamics of the Ce(IV)-catalyzed Belousov-Zhabotinsky (BZ) system has been spectrophotometrically monitored at 20.0 °C in unstirred batch conditions by using cuvettes with different geometry. The cuvette path length has been varied from 1 to 0.02 cm. The experimental results have shown that when the cuvette path length is in the range 1-0.05 cm the BZ system exhibits a chaotic behavior while below the critical value of 0.05 cm the dynamics of the BZ system is periodic. These trends have been ascribed to the elimination of the convective effect below a critical threshold and unambiguously demonstrate that convection is a bifurcation parameter for the route to chaos.
