Question

You watched the lab demo video and looked over the lab sheet. You saw how the catalyst (MnO2) affected the rate of reaction as hydrogen peroxide (H2O2) broke down in to water (H2O) and oxygen gas (O2). How did the catalyst affect the rate of reaction? What was the evidence that the catalyst was having that affect?

Answer 1

Answer:

I increase the speed of reaction.

It was observed that the reaction speed was being increased since the products were obtained in a less expected time range, that is, in less time.

Explanation:

Catalysts are those that increase the reaction rate and make the reactants quickly turn into products WITHOUT ALTERING THE NATURALITY OF THE REACTION, that is why this happened in this experiment.
