Question:

Does the nature and quality of the catalyst itself change before and after the chemical reaction?

Does the nature and quality of the catalyst itself change before and after the chemical reaction?

Answer:

The catalyst is not consumed in the chemical reaction. They are able to be separated from the reactants, either before or after the reaction. However, they may be consumed at a certain stage of the reaction and then regenerated before the end of the reaction.
A catalyst will induce a chemical reaction to change, leaving the chemical reaction faster or less
No, but in some cases it may produce catalyst poisoning
Will not change! In fact, the catalyst in the chemical reaction is to participate in the reaction, but in the reaction it not only participate in the reaction, but also generated, and the amount of reaction and the amount of equal, the total amount of the same, this process is more complex, But sometimes the problem will appear, but the information will be very clear, will not affect the problem!
