- Q: Why the amount of catalyst is too small will make the chemical reaction rate slowed down
- Can significantly change the reaction rate and its own chemical properties and quantity in the reaction before and after the basic material unchanged. The catalyst has a positive catalyst (i.e., accelerates the reaction rate) and a negative catalyst (i.e., reduces the reaction rate), and generally does not specifically refer to both the positive catalyst.
- 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: The concept of catalyst in high school chemistry
- Since the catalyst can only change the chemical reaction rate, the catalyst can not increase the mass of the product. The quality of the product depends only on the quality of the reactants.
- Q: What is the maximum impact of the chemical reaction rate? Such as catalyst, temperature, concentration. If you can, you can row order.
- Temperature and concentration also depends on the specific circumstances of the situation
- Q: What are the catalysts that appear in the chemistry experiment?
- Oxygen Oxygen Oxygen Oxygen also used when the catalyst is manganese dioxide MnO2
- Q: Can manganese dioxide do any catalyst for chemical reactions?
- The catalyst is selective
- Q: I think doubling the concentration of catalyst will double the rate of a reaction (K2/K1 =2). I want to confirm. This is for my project work. Please reply as soon as possible.
- A catalyst speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy, thus increasing the number of collisions that can result in the formation of product. When the catalyst is a reactant in the rate determining step, and the reaction is first order in the catalyst, then a doubling of the concentration will double the rate. But if the rate determining step which includes the catalyst is not first order, then doubling the concentration won't double the rate. Then there is the case of a heterogeneous catalyst in which the reaction is essentially zero order in the catalyst. The amount of catalyst won't affect the speed of the reaction beyond the initial increase. The mere fact that the catalyst is present speeds up the reaction.
- Q: about 1-3 sentences on this will do thank you
- a catalyst is something that makes a reaction go faster than it normally would. An enzyme is a catalyst; it has all the parts for the reaction on it and help organic materials break down or transfer energy or whatever reaction it needs.
- Q: how does the amount of a catalyst affect reaction rate?
- A catalyst is actually a necessary part of the reaction. The catalyst is different on in that the catalyst returns to its original state when the catalyzed reaction completes. But that means that for each atom or molecule that goes through this reaction, there must be an atom or molecule of the catalyst to combine with. You could think of the catalyst as the buses that carry the reactants to their goal. The more buses, the faster the reactants reach their goal, but at the end, all the buses are empty, just like they started.
- Q: Why can some catalysts be reused in (chemistry)?
- Because the catalyst in the chemical reaction before and after the quality and chemical properties have not changed, so in the chemical reaction can be reused.
