Q:Is there a catalyst for a chemical reaction?

There may be many, but some of the catalytic effect of the catalyst is good, and perhaps some of the catalyst has not been found

Q:In the chemical calculation, the quality of the catalyst should not be counted before and after the reaction

Half is not easy to save trouble

Q:What is the superiority of the catalyst compared to the stoichiometric reagent?

Specificity: an enzyme can only catalyze one or a class of substrates, such as proteases that catalyze the hydrolysis of proteins into polypeptides;

Q:The role and significance of chemical catalysts

The catalyst changes the reaction rate of other substances, the single said to increase the reaction rate, but before and after the reaction of chemical properties and quality unchanged, can be used repeatedly

Q:The beginning of the chemistry plus the catalyst and the plot without the Cuihua agent

Plus the rate of fast

Q:Are biological enzymes harmful to humans?

A biological enzyme is a biocatalyst that is produced or extracted from a biological organism. The catalyst is a substance that accelerates the chemical reaction and does not change itself in the chemical reaction. In layman's terms, the catalyst is a special substance that catalyzes it. Enzyme as a member of the catalyst family has its own special properties. Each of the biological enzymes will only selectively react to some chemical reactions. A biological enzyme is equivalent to a key that opens a complex compound whose importance is that its unique structure or multidimensional shape matches a part of the group. Once these two parts are combined, the specific chemical bond in the group molecule changes as if the lock was opened. When the reaction is completed, the enzyme is released and repeated with the next group, followed by repeated repeats. Many chemical reactions in the normal temperature conditions, the reaction is very slow so that the whole process is difficult to be perceived.

Q:describe a biological catalyst?

A biological catalyst is a subclass protein called an enzyme. Enzymes are biological catalysts that increase the rate of chemical reactions. A catalyst does the following: 1) Increases the rate of reaction 2) Is not itself changed at the end of the reaction 3) Does not change the reaction or its final result The amount of energy required for this reaction is called activation energy. The enzyme lowers the activation energy necessary for the reaction to take place, thus speeding up the process.

Q:Will the catalyst change in the chemical reaction?

The role of catalyst refers to the chemical reaction in the catalytic role of the reagent, of course, the catalytic effect can be divided into two kinds, one is to speed up the progress of the reaction, one is to inhibit the progress of the reaction, the specific role of the catalyst to see the actual reaction needs.

Q:Can some chemical reactions have a variety of catalysts that are correct or wrong?

Very correct, many reactions can have a lot of catalyst. Such as hydrogen peroxide decomposition can be used manganese dioxide or fe destroy

Q:What is the reaction in chemistry?

Industrial production of ammonia, ethanol, industrial synthesis of ammonia, ethanol catalytic oxidation, acetaldehyde oxidation into acetic acid, ethyl acetate preparation, the transformation of automobile exhaust, benzene substitution reaction and addition reaction, some other addition reaction of hydrocarbons, Ethanol dehydration to produce ethylene and so on
