Q: Hydrogen and oxygen in the role of the catalyst can do the chemical formula of aviation fuel?: 2H2 + O2 = catalyst = 2H2O

Q: Biological enzymes and chemical catalysts of the differences in the source, nature and catalytic characteristics of the different, specific point: Catalyst catalytic reaction relative conditions higher, selectivity than biological enzymes

Q: Is it faster or slower? The What if you do not?: 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.

Q: What is the chemical nature of the enzyme?: Enzyme protein and cofactor are present in the absence of catalytic activity, only these two parts together to form a complex to show the catalytic activity of this complex called the whole enzyme. Some enzymes cofactor is the metal ion, some enzyme cofactor is Organic small molecules in these organic small molecules, where the enzyme and protein binding is called the auxiliary base; and with the enzyme protein binding was more relaxed, dialysis can be used to separate the enzyme protein is called coenzyme. There is no strict boundary between the base and the coenzyme, the role of the metal ion in the enzyme molecule, or as a component of the active site of the enzyme, or the conformation necessary to form the center of the enzyme, or between the enzyme and the substrate The same coenzyme is often able to bind to a variety of different enzyme proteins, the composition of a variety of catalytic functions of different enzymes, such as coenzyme Ⅰ (NAD +) can be a variety of enzymes, As a coenzyme for many dehydrogenases, but each enzyme protein can only bind to a specific coenzyme into a whole enzyme.It can be seen that the specificity of the enzyme is the enzyme protein part of the coenzyme in the enzymatic reaction is usually responsible for electrons, atoms Or some chemical groups to determine the nature of the reaction.In recent years, it has been found that, in addition to proteins, some RNA and DNA molecules also have a catalytic effect on the chemical nature of the enzyme is the concept of protein produced a strong impact . However, the now known enzymes are essentially protein-based, or protein-dominated core components, and the concept that the enzyme is a protein-based biocatalyst does not exclude the presence of other types of catalysts, and more precisely, Can be given to the enzyme under the definition of: the enzyme is a kind of biological activity and special space conformation of biological macromolecules, including protein and nucleic acid.

Q: Why is the catalyst in the chemical balance, the rate of change and balance?: But the positive reaction rate is accelerated, but also speed up the reverse reaction rate, the two increase the same multiple, so the system is still in a stable state, the same balance.

Q: What is the difference between electrocatalysis and general chemical catalysis?: General chemical catalysis is a catalyst, and electrocatalysis also need to be carried out under the conditions of the electric field

Q: Can a catalyst react with a reactant?: Exactly no. A catalyst just provides a shortcut to a reaction and thats is by combining with the reactant and at end of reaction it splits from the reactant it combined with.if a catalyst reacts then it is not a catalyst

Q: The greater the chemical adsorption strength, the catalyst activity changes: If the adsorbent is a reactant, then the better the adsorption capacity of the better catalytic effect; but the catalyst surface of the product will generally have adsorption, if this effect has become very strong, then desorption The process will become difficult, the catalytic effect will decline; the other one, if the adsorption of other substances, such as the reaction may produce a reaction or the catalyst will poison the material, it is greatly detrimental to the catalytic effect. The effect is to be controlled in a suitable optimum range for superior, and preferably to be selectively adsorbed.

Q: how can you tell when a substance serves as a catalyst?: It makes a reaction run faster and better AND it is not used up by the reaction

Q: If the college entrance examination questions related to whether the catalyst involved in the reaction, how should I answer. (We must college entrance examination, I hope you help out, thank you.): The catalyst was involved in the reaction, but the physical and chemical properties did not change before and after the reaction.
