- Q:okay im doing a project for my classroom about catalyst and i have to draw a picture but when i looked up on google i just saw a bunch of random stuff and a couple were metal so thats why im asking this question. :)
- a okorder /...
- Q:how could scientists know the exact catalyst for every reactions??? THANX sooo much
- Believe me, nema, there's no way that we chemists know the best catalyst for every reaction. That would be simply impossible. However, from the type of reaction, the reactants, products, reaction conditions, solvents, etc. and from one's experience and the literature (papers and patents) one can get a good idea for most reactions of the type of catalyst that has worked for similar systems. One then starts off with a catalyst from the literature and modifies or changes it if improvement is needed based on chemical principles that one learns. There are also some theoretical calculations that can be made. Sometimes they work and sometimes they don't :) If it is an industrially important process like the Haber process for making ammonia from nitrogen gas and hydrogen gas, there may be thousands of catalysts which have been tried and evaluated. New minor improvements are being made every day. When a company does find a very good catalyst for an important reaction, often they keep it a trade secret. The good catalyst can make a huge difference in how commercially successful a particular process is. That's a large part of what chemical engineers do. You may never know if you have the best catalyst. The most you can hope for is one that is good enough. So it's a few parts personal knowledge, a few parts literature, a couple of parts theory, a lot of experimentation and often, more than not, a little luck. :)
- 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.
- your O2 sensor measures the amount of oxygen remaining in the exhaust gas after the combustion process. The left over oxygen reacts with the sensor to send an electrical signal to your vehicles computer. the computer can then adjust your fuel injector pulse width in order to maintain the proper 14.7:1 air/fuel ratio. Excessive exhaust gases are the usual culprit when catalatyc converters fail. Even so the O2 sensor is usually fairly cheap ($20-$30) and simple to replace. I would replace it as cheap insurance
- Q:If possible can anyone give me information on the active site, substrates, products, and the energy of activation as part of the answer?Responses greatly appreciated! Thankss! 10pts to best answer!
- Catalysts help shift the equilibrium of a reaction to one that is more favorable. They allow a naturally occurring reaction that may be extremely slow to progress faster or an unfavorable reaction to proceed forward. During the process catalysts are recycled, which means that at the catalyst is the same compound in the beginning and the end of the reaction, although during intermediate steps catalysts can change conformation. Catalysts shift the equilibrium of a reaction by lowering the activation energy of a reaction, which is the energy barrier which must be overcome in order for the reaction to proceed in a desired direction. This can be achieved in several ways such as providing favorable thermodynamic conditions for a reaction or creating intermediates which react more favorably to create the products. Inside the cell a lot of chemical reactions are either too slow to proceed naturally or are simply unfavorable. Catalysts help overcome those barriers. The substrate is the part of the reaction which gets transformed into the products after binding to the active site of the protein.
- Q:Please help me
- enzymes are like chemical scissors that break up starch inside your body they work best at 37'c which is body temperatur i think they are in the stomach? don't know for sure hope this helped as for catalysts i dont know
- Q:The role and significance of chemical catalysts
- The catalyst changes the reaction rate of other substances, the single said to increase the reaction rate, but before and after the reaction of chemical properties and quality unchanged, can be used repeatedly
- Q:What is the catalyst in the end?
- You said the chemical catalyst or Ati graphics card catalyst? If the above is enough to explain the above, if it is the latter, that is, the meaning of the graphics card, Ati's graphics drive like a catalyst
- Q:in my 99 ram 2500 v8 5.9 that code came up, not sure what to do about it or what it could be any ideas or help with be great thanks
- In after Robert M phaggotry. Oh, like that first poster said, be sure there aren't other faults causing the rear O2 sensor to pick up all that O2 in the exhaust...such as a rich-running engine.
- Q:Will the catalyst change in the chemical reaction?
- The catalyst is actually involved in the chemical reaction, the catalyst is added to the reaction, becomes the other material, and then the reaction becomes back, and appears to have no change, actually involved in the change, but the end result the catalyst did not change
- Q:Comparison of biocatalysts with chemical catalysts!
- 4, some of the catalytic activity of biological enzymes and related factors .5, most of the enzymes are proteins, which will be high temperature, strong acid, alkali and other broken
