Abstract
Our previous mechanistic model for the Belousov–Zhabotinsky reaction has been revised to include a more realistic set of reactions for the oxidation pathways of the organic intermediates. A few other rate constants have also been modified to include new information. The revised mechanism reproduces the essential experimental observations, although the periods of oscillation are somewhat too long and oscillations cease at malonic acid concentrations about ten times greater than the observed lower limit. However, the essential features of the mechanism are clearly understood.

The photo-induction of chemical oscillation has been found in the Belousov-Zhabotinsky reaction in a continuous flow-stirred tank reactor. Photo-response of the system is characterized by taking the initial concentration of bromate ions and the incident light power as external control parameters. Th
In a stirred batch reactor, the Ce(III)-or Mn(II)-catalyzed Belousov-Zhabotinsky reaction with mixed organic acid/ketone substrates exhibits oscillatory behavior. The organic acids studied here are: dl-mandelic acid (MDA), dl-4-bromomandelic acid (BMDA), and dl-4hydroxymandelic acid (HMDA), and the
