Question:

Chemical catalyst

The catalyst before and after the reaction of the quality and nature of the same, does it mean that a little catalyst can be all the substrate reaction? Such as: one gram of MnO2 can reflect the infinite H2O2?

Answer:

There are positive catalyst and anti-catalyst, as well as the amount of catalyst is also related to the rate, not the more the better
Catalyst before and after the reaction of the same quality,
Catalyst reaction is essentially involved in the reaction, we learn the chemical reaction is simplified, in fact, most of the reactions are to go through several processes to form, because it is more complex, we learn to write directly reactants and products , The reaction is saved in the middle of the catalyst is involved in the middle of the reaction process, in the final process and generated, to achieve the effect of catalytic reaction, its own quality and nature has not changed.
The quality of the catalyst before and after the reaction
