- Q: Chemistry GCSE what is a catalyst?
- A substance that speeds op a chemical reaction...*
- Q: Chemistry is often said that the catalyst can change the material reaction rate, rate and speed What is the difference
- The rate is related to the concentration of matter, the velocity is physically, is the vector, has the direction
- Q: Can some chemical reactions have a variety of catalysts that are correct or wrong?
- Very correct, many reactions can have a lot of catalyst. Such as hydrogen peroxide decomposition can be used manganese dioxide or fe destroy
- 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: 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: Does increasing the amount of catalyst added to, say, a solution of Hydrogen Peroxide, make the rate of reaction go faster. Is the rate of reaction directly proportional to the amount of catalyst added to the solution? Or does the experiment go at the same rate regardless of how much catalyst there is? Thanks would really appreciate some answers. - Sarah
- Catalyst do not participate in the reaction but it speeds up the reaction. If you increase the amount of catalyst from the required amount, it would somehow negates its positive response or it would result in producing another product.
- Q: how can you tell when a substance serves as a catalyst?
- The purpose of a catalyst is to provide an alternate pathway for a reaction to proceed, often one with a lower activation energy, such that the reaction will generally proceed faster. The key to catalysts if they they are NOT consumed by the reaction in the end (they may be consumed in an intermediary step, but if so, a subsequent step will recreate the catalyst). In other words, catalysts do not actually participate in the reaction, so they may be reused when the reaction has completed.
- 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 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 to catalyze the presence of magnesium oxide, iron oxide and copper oxide and so on.
- Q: Is it not the rate to accelerate the addition of the catalyst to the catalyst, and that is why the balance does not move
- If the reaction before the catalyst, you can speed up the reaction rate, that is to achieve the balance required to reduce the time, but to balance the system when the same concentration
- Q: Write a chemical formula in a chemical laboratory without the use of a catalyst for oxygen
- 2KMnO4 ==== K2MnO4 + MnO2 + O2 ↑
