Methods to determine activation energies for the two kinetic states of the oscillatory Bray-Liebhafsky reaction

Abstract

Six different methods are suggested to calculate the apparent activation energies of the overall decomposition of hydrogen peroxide, both by oxidative and reductive pathways, in the Bray-Liebhafsky oscillatory chemical system. The activation energies of the reduction pathway lie between 31 and 35 kJ/mol and those of the oxidation one between 75 and 78 kJ/mol. © Akadémiai Kiadó, All rights reserved.
