Belousov-Zhabotinsky oscillatory reaction: Kinetics of malonic acid decomposition

Abstract

The kinetics of the Belousov-Zhabotinsky (BZ) oscillatory reaction was analyzed. With this aim, the time evolution of a reaction mixture composed of malonic acid, bromate, sulfuric acid and cerium(III) was studied at 298 K. Pseudo-first order kinetics with respect to malonic acid as the species undergoing decomposition with a corresponding rate constant, k = 7.5x10-3 min-1, was found.

Sa ciljem da se analizira kinetika Belousov-Žabotinski oscilatorne reakcije, proučavana je vremenska evolucija reakcione smeše koja se sastoji od malonske kiseline, sumporne kiseline i cerijuma(III) na 298 K. Nađena je kinetika pseudo-prvog reda u odnosu na malonsku kiselinu kao vrstu koja podleže razlaganju i odgovarajuća konstanta brzine, k = 7.5x10-3 min-1.
