Abstract: The parameters of oscillating reaction depend on the efficiency and intensity of saturation of the reaction solution with oxygen, which is given by oxygen concentration in bubbling gas, flow of gas, method of gas introduction into solution, stirring, and temperature. The increase in apparent activation energy is due to the decrease in ratio of the rate of saturation of solution with oxygen to the average rate of substrate oxidation at increasing temperature. The dependence of the number of oscillations on nitrogen flow exhibits several maxima. The concentration oscillations of manganese(II) were investigated by the circulation ESR technique.
