WebThe conclusion that the reaction rate is limited by a chemical reaction at the MnO 2 surface is supported by: (1) an apparent activation energy of 35.9 kJ/mol (8.6 kcal/mol), (2) the inverse first-order relationship between the rate constant k and the initial particle diameter, (3) the independence of the reaction rate on stirring speed and ... Weboxidizing agent is Mn and the element that gets reduced is O. The half-cell oxidation reaction is Mn2+ + 2H 2O = MnO2 +4H + + 2e and the half-cell reduction reaction is 1/4 O 2 + H + + e = ½ H 2O.
