give an example of how a catalysts speeds up the rate of reaction?? thank you!!?
When making margarine, nickel is used to speed up the process.
I like the hydrogen peroxide answer, but I just ran out of MnO2 at my house, I guess I will just have to pour some H2O2 into the small cut I have. The bubbles you see are oxygen gas which is formed by the decomposition of the H2O2 catalyzed by the peroxidase enzyme in your blood.
Catalysts speed up a reaction, but at the end of it, it's chemically unchanged. You usually have the same mass at the end of the reaction. For example.. Consider the decomposition of Hydrogen Peroxide: 2H2O2 -2H2O + O2 I hope you got how to represent it =D So.. This reaction is very slow. You can try it out in the lab. So when we add a catalyst, the reaction speeds up. The catalyst used here is MnO2.. Manganese dioxide. Well.. The Enzymes in our body are also Catalysts. They speed up the Biological Reactions taking place inside out body. I hope this answers your question. :) Cheers
