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 order is found 0.5 and 1 with respect to hydrogen peroxide and chlorate concentration, respectively. Reaction order is found about 5.99 with respect to molar concentration of sulfuric acid, but it reduces to 1.64 when acidity function(h_), is substituted in place of molar concentration. The reaction is a process of leat absorption and the activation energy is about 105kJ/mol. Reaction mechanism shows it is a self-catalyze reaction.
