Abstract :
The reaction between hydrogen peroxide and sodium chlorate in presence of aqueous sulfuric acid was studied at various temperatures and molar concentrations of hydrogen peroxide, chlorate and sulfuric acid. The reaction rate law was established by analyzing the consumption of chlorate or hydrogen peroxide. Reaction had been found 0.5 and 1 order with respect to hydrogen peroxide and chlorate concentration, respectively. Reaction order was found about 5.99 with respect to molar concentration of sulfuric acid but it reduced to 1.64 when acidity function, h-, was substituted in place of molar concentration. The temperature dependence of the reaction was also investigated and pre-exponential Arrhenius parameter as well as activation energy were determined. Reaction mechanism compatible with the reaction kinetics was proposed.
