Autor: LJILJANA KOLAR-ANIC, SLAVICA BLAGOJEVIC, NATASA PEJIC, NEBOJSA BEGOVIC, STEVAN BLAGOJEVIC, SLOBODAN ANIC

Publikováno v: Journal of the Serbian Chemical Society, Vol 71, Iss 6, Pp 605-612 (2006)

Some new experimental evidence of complex irregular oscillations in the Belousov–Zhabotinsky reaction realized in a batch reactor is presented. The results were obtained under relatively low cerium and malonic acid concentrations. One-dimensionalma

Belousov-Zhabotinsky oscillatory reaction. Kinetics of malonic acid decomposition

Autor: LJILJANA KOLAR-ANIC, SLOBODAN ANIC, NATASA PEJIC, SLAVICA BLAGOJEVIC

Publikováno v: Journal of the Serbian Chemical Society, Vol 65, Iss 10, Pp 709-713 (2000)

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 kinetic
