- Q: Carbon dioxide and hydrogen in the catalyst and heating conditions, the reaction of water and methane, the chemical equation is what
- CO2 + 4H2 = catalyst, heating = 2H2O + CH4
- Q: What is the effect of the catalyst in chemistry?
- In fact, the catalyst in the chemical reaction is not the reaction of the role, but to play a role in accelerating the speed of chemical reaction, it is like a reaction to an hour, but joined a certain catalyst, the reaction speed A lot, as long as half an hour to react to play, the catalyst as long as properly handled, but also can be recycled, the students do not have any chemical changes
- Q: in acid-catalyzed reaction,there are some books show the acid catalyst as H+ and there are some show it as H3O+ .Are they the same?
- Sort of. If the reaction is under aqueous conditions (any water is included in the reaction), then yes, H+ = H3O+. This is because free protons present (H+) will be coordinated generally to molecules of water [thus H2O + H+ =H3O+ ]. But there are reaction conditions where water is not present, but an acid catalyst is still possible. In these cases, the acid catalyst may frequently be indicated as simply H+. Either way, the function in most of your reaction mechanisms is basically the same, whether indicated as H+ or H3O+ -- and that's to protonate molecules (Lewis or Bronsted bases) with H+. Concentrated sulfuric acid would be an example of a mostly-anhydrous (no water) strong proton/acid source (H+). Hydrochloric acid (HCl) frequently is available as an aqueous solution, even concentrated HCl is an aqueous solution of HCl. HCl itself is a gas under ambient conditions... but it has solubility in water and thus is conveniently sold frequently as an aqueous solution (which could be represented as H3O+)
- Q: Please help me
- A catalyst is a substance which is used to increase or decrease the rate of a reaction, without itself undergoing any chemical change. There are two types of catalysts, positive and negative. Positive catalysts are used to increase the rate of a reaction while negative catalysts are used to decreasing the rate of a reaction. Enzymes are proteins which act as catalysts in biochemical reactions. They operate between a certain pH level and temperature. If there is a change in pH level or temperature, their efficiency decreases.
- Q: What are the properties of the catalyst (eg, specificity)?
- The definition of a chemical reaction in the chemical reaction can change the chemical reaction rate of other substances, and its quality and chemical properties before and after the reaction did not change the material called catalyst, also known as catalyst. Catalyst in the role of chemical reaction 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 are more reactive than the original reaction The reaction conditions of the catalyst have been changed by the reaction of the catalyst by the reaction of the catalyst, that is, the quality and chemical properties mentioned above did not change before and after the reaction.
- Q: Why are catalysts so effective in small amounts?
- Catalysts don't get used up in reactions. Because of this, a single catalyst molecule can function again and again. Some catalysts are better than others for a given reaction. More effective catalysts reduce the time taken for 1/ the rate of travel of the molecule to the active site, 2/ the time the reaction takes, or 3/ the time it takes for products to diffuse away, or 4/ a combination of the above. The more effective a catalyst is in these factors, the less is needed to make it equally effective.
- Q: Explain how catalysts help to reduce costs in industrial processes !?Thanks
- They speed up a reaction, allowing you to get more product more quickly and remain unchanged, therefore you can use them over and over again.
- Q: What are the methods of catalyst characterization?
- Physical means, is commonly used detection means, infrared, ultraviolet, electron microscopy, X-ray diffraction, nuclear magnetic, etc., of course, including a variety of conventional inability analysis.
- Q: Chemical reactions in the presence of impurities will cause catalyst poisoning, how to understand this sentence
- Catalyst poisoning reaction of raw materials contained in the trace impurities to the catalyst activity, selectivity significantly decreased or lost phenomenon. The nature of the poisoning phenomenon is a trace of impurities and the catalytic activity of the center of a chemical effect, the formation of non-active species. In the gas-solid heterogeneous catalytic reaction is formed in the adsorption complex. One is that if the toxic and active components of the role of weak, can be a simple way to restore the activity, known as reversible poisoning or temporary poisoning. The other is irreversible poisoning, it is impossible to restore the activity in a simple way. In order to reduce the side reaction activity, it is sometimes necessary to allow the catalyst to be selected for poisoning.
- Q: I have just spent CAN$550 to replace a catalyst converter at one end of the muffler. The repairman said I need to replace the oxygen sensor very soon, otherwise, the C.C. will be gone again. Is that true... can someone confirm this for me. Thanks.
- The oxygen sensor senses whether the exhaust coming out of the engine is clean of emissions gasses. It can also alter the air-fuel mixture in the engine to run leaner or richer. And yes, it's always a good idea to change the oxygen sensor when changing the c.c. because it can damage the c.c or other components in your engine.
