Chemical reaction in the presence of catalyst for the reaction are carried out a high life
Theoretically are carried out, but some of the reaction is relatively slow, so we classified it as non-response, the catalyst is only to speed up or slow down the reaction rate of the reaction itself does not affect the reaction. I'm on high school.
Juvenile high school you have to learn the reaction are hundreds of I can not tell you one by one you will learn some of the time can be added plus no plus can not respond
Some reactions require some of the catalyst that is not needed
