Question

The decomposition of hydrogen perioxide occurs at a faster rate on adding powder as a catalyst.​

Answer 1

Answer:

I hope this helps you ☺️

please mark me brilliant

Explanation:

Reaction of decomposition of hydrogen peroxide is very slow in moderate temperatures without the presence of a catalyst [11]. It can be sped up by increasing the temperature, which triggers the reaction of thermal decomposition. This reaction can be carried out in a liquid or vapour phase.

Answer 2

Answer:

Hope it helps you mate.

Explanation:

At room temperature, the decomposition of hydrogen peroxide into water and oxygen takes place slowly. However, the same reaction occurs at a faster rate on adding manganese dioxide (MnO2), powder in it. Where MnO2 reacts as the catalyst thereby increasing the rate of reaction.
