Some chemical reactions are not only the only catalyst, such as potassium chlorate can be thermally decomposed to catalyze the presence of magnesium oxide, iron oxide and copper oxide, etc. The definition of the chemical reaction can change the chemical reaction rate of other substances in the chemical reaction , And its own quality and chemical properties before and after the reaction did not change the material called catalyst, also known as catalyst. Catalyst in the role of chemical reaction called catalysis
The relationship between it and the reaction system is as highly selective (or specific) as the relationship with the key. A catalyst does not catalyze all chemical reactions, such as manganese dioxide in the decomposition of potassium chlorate Play a catalytic role to speed up the chemical reaction rate, but the other chemical reactions do not necessarily have a catalytic effect
The catalyst is a substance that can change the rate of the reaction without changing the standard of the reaction Gibbs free, according to the definition of the International Pure and Applied Chemistry (IUPAC) in 1981, Enthalpy change. This action is called catalysis. The reaction involving the catalyst is a catalytic reaction. The catalyst will induce a chemical reaction to change, causing the chemical reaction to become faster or slower or to undergo a chemical reaction at a lower temperature The catalyst is also known as a catalyst in industry, and the composition, chemical properties and quality of the catalyst itself do not change before and after the reaction;
