Q: The addition of the catalyst has no effect on the chemical equilibrium of the movement: Factors that affect the chemical balance of movement are mainly concentration, temperature, pressure and so on.

Q: What is the similarity between enzymes and general chemical catalysts?: (1) The enzyme is the same in many respects as a biocatalyst and a general catalyst, such as a small amount and a high catalytic efficiency. As with the general catalyst, the enzyme can only change the rate of chemical reaction and does not change the equilibrium of the chemical reaction It is possible to catalyze the activation of a large number of substrates in a short time and to reflect the high efficiency of enzyme catalysis.The enzyme can reduce the activation energy of the reaction (activation) (△ G) during the reaction, but the reaction rate is accelerated and the reaction time is reduced, but the equilibrium constant is not changed. (2) However, the enzyme is a biological macromolecule (1) Enzyme-catalyzed high efficiency: The catalytic effect of the catalyst can increase the reaction rate by 10 ^ 6 ~ 10 ^ 12 times, which is at least several times higher than that of the conventional catalyst. (2) The enzyme catalyst Highly specificity: including specificity of response, substrate specificity, chirality specificity, geometric specificity, etc., that an enzyme can only act on a certain class or a specific substance. Bond, ester bond, peptide bond and so on can be catalyzed by acid-base hydrolysis, but the hydrolysis of these chemical bonds are different, respectively, the corresponding glycosidase, esterase and peptidase, that is, they were specific (3) enzymatic reaction conditions are mild: enzymatic reaction is generally carried out in aqueous solution of pH = 5 ~ 8, the reaction temperature range is 20 ~ 40 ℃

Q: what is the role of a catalyst in a chemical reaction?: A catalyst speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy. Since the activation energy is lower, more product will be formed in the same amount of time. Chemists used to assume that a catalyst somehow sped up a reaction without being consumed in the reaction. We now know that a catalyst will be a reactant in one step of a reaction mechanism, and will be a product in a subsequent step in the mechanism, so that it **appears** that the catalyst does not take part in the reaction. ======== Follow up ========= Remember, it is customary to cite one's sources when quoting from another source or when simply copying large passages from Wikipedia or some other web page.

Q: Exemplify the use of green catalysts in green chemistry: The role of the catalyst is to control (speed up or slow down) the rate of chemical reactions. If you have to add a "green", perhaps this catalyst also requires not to pollute the environment or harmful to humans. Such as fertilizer used in the manufacture of platinum catalysis should belong to this.

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: What is the catalyst for ethylene addition water? How to play a catalytic role.: Phosphoric acid or sulfuric acid, 280 to 300 ° C, 7 to 8 MPa

Q: Does the nature and quality of the catalyst itself change before and after the chemical reaction?: A catalyst will induce a chemical reaction to change, leaving the chemical reaction faster or less

Q: In the chemical reaction will have to use the catalyst reaction, such as H2O2 === (MnO2) H2O + O2 ↑, then the catalyst in the end to participate in the reaction (that is, the catalyst itself is the reactant) If so, why are some of these substances in the reaction (these substances refer to the catalyst) in the reaction after the quality and nature of the change does not change?: The definition of a chemical reaction rate in a chemical reaction can be changed (accelerated or slowed down) in a chemical reaction, and the quality and chemical properties of the substance itself are not catalyzed before and after the reaction (which will change during the reaction) Also known as catalyst. Its physical properties may change, for example, MnO2 in the catalytic potassium chlorate to generate potassium chloride and oxygen before and after the reaction from the block into a powder. There is also a saying that the catalyst reacts first with one of the reactants and then the two products continue to undergo a new chemical reaction under the original conditions and the reaction conditions of the catalyst reaction product are more favorable than the reaction conditions of the original reactants Changed.

Q: Chemical reaction in the presence of catalyst for the reaction are carried out a high life: Juvenile high school you have to learn the reaction are hundreds of I can not tell you one by one you will learn some of the time can be added plus no plus can not respond
