- Q: High school knowledge __ teacher do not know right!
- Nothing to do, but with the percentage of activated molecules, is proportional to
- Q: When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
- No need, because the catalyst in the chemical reaction before and after the quality of the same
- Q: What is the principle of the catalyst? Why can change the rate of chemical reactions and their own without any change
- The catalyst is a substance that alters the reaction rate without changing the total standard Gibbs free energy of the reaction. The composition, chemical properties and quality of the catalyst itself do not change before and after the reaction; its relationship with the reaction system is as highly selective (or specific) as the relationship between the lock and the key. A catalyst does not catalyze all chemical reactions. For example, manganese dioxide catalyzes the thermal decomposition of potassium chlorate, accelerates the reaction rate, but does not necessarily have a catalytic effect on other chemical reactions. Some chemical reactions are not only the only catalyst, such as potassium chlorate can be thermally decomposed in the catalytic role of magnesium oxide, iron oxide and copper oxide, etc., potassium chlorate oxygen can also be used when the red brick powder or copper oxide as a catalyst.
- Q: What is the chemical vinyl chloride and benzene plus catalyst?
- Looks like no ethyl benzene, it is vinyl benzene
- Q: What are the characteristics of the catalyst in the chemical reaction?
- In simple terms: the catalyst itself is involved in the reaction, the quality of the reaction before and after the same, the ingredients do not change. The catalyst can change the rate of chemical reaction, increase the rate of reaction called catalyst, slow the inhibitor.
- Q: Is the catalyst in the chemical reaction better?
- If the concentration of the liquid is too low, then the catalyst is also ineffective
- Q: What is the relationship between the catalyst and the chemical reaction? What is the relationship between the enzyme and the catalyst?
- Catalytic, also known as catalyst, is defined in the junior high school stage to be able to change the rate of chemical reactions, and its own quality, composition and chemical properties remain constant before and after chemical reactions. For example, manganese dioxide can be used as hydrogen peroxide (hydrogen peroxide) decomposition of the catalyst. The catalyst is divided into the positive catalyst and the catalyst is used. The positive catalyst contributes to the reaction to move in the positive direction, and the reverse catalyst contributes to the reaction to move in the reverse direction.
- Q: Word editor when playing chemical equation = with the above conditions or how to adjust the size of the catalyst, how to make it centered,
- Open the word - insert - object - WPS3.0 formula - and then select the "label arrow template", you can add a catalyst.
- Q: What is the analytical principle of chemical adsorbents? How about the number of active catalyst centers tested?
- What do you mean by the chemical adsorber? BET is the use of the surface of the uneven force field, but the inert gas at low temperature in the surface adsorption. TPD, TPR is the number of active centers that can be measured by the technique of desorption and reduction between specific gases and catalysts as the temperature increases. If the active site is a reduced position, H2-TPR can be used. If the active site is acidic, NH3-TPD can be used, but also the method of alkali titration.
