Answer:
Manganese dioxide catalyzes the decomposition of hydrogen peroxide to oxygen and water. ... With the addition of the synthesized catalyst, MnO2, we can actually lower this activation energy down to about 58 KJ/mole (Moelwyn-Hughes) and that speeds up the decomposition by 1073 times at 200C.
