hydrogen peroxide occurs at a
faster rate on adding
as a catalyst.
*
O nickel
O potassium permanganate
O manganese dioxide
O ozone​

Answer 1

Answer:

potassium permanganate

Explanation:

The catalytic decomposition of hydrogen peroxide provides a range of project opportunities of varying length and complexity. This is because of the variety of catalysts that will increase the rate of decomposition and the methods that can be used to monitor the reaction:

2H2O2 → 2H2O + O2
