Is it faster or slower? The What if you do not?
The catalyst is divided into: positive catalyst and negative catalyst, positive catalyst accelerates the reaction rate, and negative catalyst slows down the reaction rate. Regardless of the positive and negative of the catalyst, it only changes the rate of the reaction, does not change the nature of the reaction, and the reaction, the chemical nature of the catalyst will not change!
The junior middle school textbook is defined as "no reaction" but in fact the catalyst reacts first with a reaction and then the product reacts with other reactants, which will speed up the rate of reflection. Not all catalysts can speed up the reaction rate, but the organic catalyst is more efficient than the inorganic catalyst. "Hydrogen peroxide reacts with hydrogen peroxide more quickly than hydrogen chloride reacts with hydrogen peroxide.
Positive catalyst is to speed up the negative catalyst to slow down some reaction must be used to the catalyst otherwise difficult to react
Reduce or increase the energy required for the reaction, can also slow down, do not have no effect on the reaction
