REACTION RATE OF PEROXIDE WITH POWDERED MnO2 (4 of 5)
Compared To Catalysis of Peroxide With Solid MnO2
4 seconds after addition of 2.5ml of 30% hydrogen peroxide to the beaker to react with 0.6g of manganese oxide powder. The reaction, compared to the reaction with a 0.6g chunk of manganese oxide , is considerably more vigorous.
