What is a catalyst
May 19, 2018


Catalyst can induce chemical reaction to change, and chemical reaction is faster or less, and the catalyst is also known as catalyst in industry.

The composition, chemical properties and quality of the catalyst do not change before and after the reaction.

The relationship between it and the reaction system is as highly selective (or exclusive) as the relationship between locks and keys.

A catalyst is not has catalytic effect to all chemical reactions, such as manganese dioxide catalytic role in the decomposition of potassium chlorate is heated, accelerate the chemical reaction rate, but for other chemical reactions are not necessarily have a catalytic role.

Certain chemical reactions are not unique to a catalyst, such as magnesium oxide, iron oxide, and copper oxide, which can be catalyzed by the thermal decomposition of potassium chlorate.

Definition: a junior high school book can change other material chemical reaction in chemical reaction rate, and the quality and chemical properties of the itself in no change before and after reaction substance called a catalyst, also known as catalyst.

The action of a catalyst in a chemical reaction is called catalysis.

Also have a saying, catalyst and reactant is one of the first, and then the two new products continue to the existing conditions of chemical reaction, the products of reaction conditions and catalyst from the original reactant reaction conditions change.

Catalyst originally generated by reaction of material will be further to regenerate the original catalyst in the reaction, after that the above mentioned quality and chemical properties in no change before and after reaction.
