If the college entrance examination questions related to whether the catalyst involved in the reaction, how should I answer. (We must college entrance examination, I hope you help out, thank you.)
The catalyst does not participate in the reaction, but play a catalytic role, if the reaction is not called the catalyst
The catalyst does not participate in the reaction, but only to accelerate, slow down the auxiliary role
The catalyst is involved in the reaction in the chemical reaction. Because it participates in the chemical reaction, it can change the course of the reaction, reduce the activation energy, increase the reaction rate, and the quality and chemical properties before and after the reaction. I hope to help you;
The catalyst was involved in the reaction, but the physical and chemical properties did not change before and after the reaction.
