The role and significance of chemical catalysts
To speed up or slow down the chemical reaction is to make the chemical reaction more direct, simple and straightforward to adopt
In the pre-chemical reaction, to speed up the reaction rate, and in the chemical reaction before and after the material quality and chemical properties are not changed.
The catalyst does not participate in the reaction, but only acts as a catalyst, and finally gets the catalyst composition unchanged. But if the catalyst, your reaction will be very slow or even not happen.
The catalyst changes the reaction rate of other substances, the single said to increase the reaction rate, but before and after the reaction of chemical properties and quality unchanged, can be used repeatedly
