What is the principle of the catalyst? Why can change the rate of chemical reactions and their own without any change
Because the catalyst does not participate in the reaction, it can change the rate of chemical reactions without any change in itself.
The catalyst can be used as the reaction of the original reaction into multiple reactions, such as two, then the catalyst can be the first reaction of the product, while the second reaction of the reactants, then the overall point of view, the amount of catalyst No change, is to change the reaction process.
If you are not asking for a written, you can look at my words. The principle of the catalyst is to make the water muddy. It has to accelerate the chemical reaction, but also slow down the reaction. Catalyst ions into the solution, is to let the solution become muddy, and then should be the reaction of the ion collision probability is large, to speed up the reaction. The substance of the catalyst does not participate in the reaction, so it does not change. Are personal understanding, wrong please more inclusive. Thank you
The catalyst is a substance that alters the reaction rate without changing the total standard Gibbs free energy of the reaction. The composition, chemical properties and quality of the catalyst itself do not change before and after the reaction; its relationship with the reaction system is as highly selective (or specific) as the relationship between the lock and the key. A catalyst does not catalyze all chemical reactions. For example, manganese dioxide catalyzes the thermal decomposition of potassium chlorate, accelerates the reaction rate, but does not necessarily have a catalytic effect on other chemical reactions. Some chemical reactions are not only the only catalyst, such as potassium chlorate can be thermally decomposed in the catalytic role of magnesium oxide, iron oxide and copper oxide, etc., potassium chlorate oxygen can also be used when the red brick powder or copper oxide as a catalyst.
The principle of the catalyst: the catalyst is mainly by reducing the activation energy, so that the reaction is easy to carry out, so as to achieve the catalytic effect.
