Reaction of a Sulphide with Hydrogen Peroxide

Bench Scale Calorimetry in Chemical Reaction Kinetics, 

It is known that acids (such as sulphuric acid, nitric acid) catalyse the first stage the second and third stages require additirmally the use of potassium permanganate or sodium molybdate as catalyst. 

To conduct the kinetic investigaliOTi, the measuring kettle of the calorimeter is filled with a batch of sulphide, Na2Mo04, H2O2 and xylene because the industrial production is run under conditions of cooling by reflux. The batch is brought to reaction temperature and H2O2 is injected simultaneously at the start of the reaction. 

Obviously, the reaction steps are not elementary reactions, because the caloric reaction power respectively rate of reaction depends only on the concentration of sulphide, sulphoxid or sulphon but does not depend on the concentration of the reactant H2O2. Such a phenomenon occurs under special conditions when the catalyst first reacts reversibly with one of the reactants (Michaelis Menton mechanism) in the present case
