Computational Simulation of Bray-Liebhafsky (BL) Oscillating Chemical Reaction
The computational simulation of the Bray-Liebhafsky (BL) oscillating chemical reaction by differential kinetic methodology is carried out in this work. According to the mechanism of Treindl and Noyes involving 10 reaction steps, the changes of the concentrations of I2 and O2 in solution are simulated. When the control parameters are α = 0.55, β = 0.2882 and δ < 0.6, the differential equations p...
متن کاملNumerical Simulation of the Behaviors of the Bray-Liebhafsky Oscillating Chemical Reaction by a Four-variable Model
Based on a ten-step chemical model involving the concentrations of I2(aq), O2(aq), and the intermediates of Iand HIO2, four independent variables and seven irreversible steps, the nonlinear behavior of Bray-Liebhafsky (BL) oscillating reaction was investigated. The results showed that with different values of initial concentrations of reactants in the process of simulation, both periodic oscill...
متن کاملThe Bray-liebhafsky and Briggs-rauscher Oscillating Reactions
The common points and differences between the Bray-Liebhafsky and BriggsRauscher reactions are discussed. The reactants of the non-catalyzed version of the Briggs-Rauscher reaction being the same as those of the Bray-Liebhafsky reaction plus a reducing organic compound, the mechanisms of these two systems must have several common points. The marked difference between the oscillating behaviours ...
متن کاملIodine oxidation by hydrogen peroxide and Bray-Liebhafsky oscillating reaction: effect of the temperature.
This work presents a new experimental kinetic study at 39° and 50° of the iodine oxidation by hydrogen peroxide. The results allow us to obtain the temperature effect on the rate constants previously proposed at 25° for our model of the Bray-Liebhafsky oscillating reaction (G. Schmitz, Phys. Chem. Chem. Phys. 2010, 12, 6605.). The values calculated with the model are in good agreement with many...
متن کاملKinetics of the Bray-Liebhafsky Oscillatory Reaction Perturbed by Polymer Supported Cobalt Catalyst
The Bray-Liebhafsky (BL) oscillatory reaction generated in the batch reactor at 6268 C was perturbed by cobalt(II)-nitrate, supported on the macroreticular copolymer of poly-4-vinylpyridine with divinylbenzene (Co-PVPDVB). The kinetic data was analyzed of the complex pathways of the hydrogen peroxide decomposition in the examined BL reaction. The obtained results confirm that the kinetics of th...
