- Q: What is the superiority of the catalyst compared to the stoichiometric reagent?
- Some enzymes are related to cofactors, and because of the fact that most enzymes are proteins, they are destroyed by high temperatures, strong acids and strong bases.
- Q: The catalyst before and after the reaction of the quality and nature of the same, does it mean that a little catalyst can be all the substrate reaction? Such as: one gram of MnO2 can reflect the infinite H2O2?
- The quality of the catalyst before and after the reaction
- Q: The role and significance of chemical catalysts
- In the pre-chemical reaction, to speed up the reaction rate, and in the chemical reaction before and after the material quality and chemical properties are not changed.
- Q: explain how a catalyst can affect the rate of reaction but not be in the overall equation.?
- a catalyst is a substance that speeds up the rate of reactions that would already happen (the reactions are spontaneous) but would take a long long time to occur. Every reaction proceeds from a level of high energy to a lower level of energy, but in order to start going downhill you need to get up, in affect getting more energy than the reactants have now. This is because the transition state, or what the reactnat/product is in the middle of the reaction, is less stable and requires more energy than the reactants. Catalysts lower the extra energy needed (called activation energy) to a level that the reactants already have, and the reaction occurs.
- Q: What is a chemical catalyst?
- A substance that participates in chemical reactions but does not change the quality and chemical properties. It can change the reactant activation energy, speed up or slow down the reaction rate.
- Q: What kind of chemical substances can seriously damage the ozone layer, as a catalyst or reactants can be?
- Freon decomposition of free radicals. The destruction of our ozone is mainly caused by him. Chlorine free radicals are also available.
- Q: When you write a chemical equation, how do you want to add "catalyst" and "?" When you do not have to write?
- This is the need for your memory, write a few times, will naturally cooked
- 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: Before and after the chemical reaction, the nature of the catalyst unchanged this statement right? Why?
- Yes, the catalyst only acts as a catalyst and does not participate in chemical reactions
- Q: How to poison the catalyst. What can be done?
- In the reactants or catalyst mixed with a small amount of material, so that the catalyst catalytic capacity of a sharp decline or even loss, this phenomenon is called catalyst poisoning. For example, in the synthesis of ammonia feed gas containing CO, CO2 and H2S, PH3, water vapor and other impurities, can make iron catalyst poisoning; contact with the system of sulfuric acid, if arsenic and selenium oxide (As2O3, SeO2), can make vanadium catalyst Loss of activity. Therefore, it is necessary to purify the feed gas, prevent the poisoning of the catalyst, and also reduce the corrosion of the equipment. The phenomenon of catalyst poisoning is sometimes temporary, the removal of toxicants, the effectiveness of the catalyst can still be restored; sometimes it is permanent, without chemical treatment can not restore catalytic performance.
