Answer to Question #179901 in General Chemistry for Nesha

Question

To determine the most efficient catalyst that decomposes hydrogen peroxide using KI, FeCl₃ and PbO₂. Possible things that i can mentioned in my discussion and reflection. Thanks in advance

Answer 1

As an interesting contrast, a similar increase in the rate of decomposition of hydrogen peroxide can be achieved using an inorganic catalyst such as manganese (IV) Oxide or lead(lV) oxide.

2H₂O₂-> 2H_{2O +} O₂

Occurs in the presence of Manganese Dioxide. MnO₂ is used in heterogeneous reaction of decomposition of hydrogen peroxide due to its good catalytic efficiency in the reaction.
