- Q:When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
- The habit of writing is not to write the catalyst involved in the equation, it is usually written in the equation above the equal or below
- 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:Are the catalysts for upgrading the weapons components that i may have a few of, or very rare ones?
- Catalysts can only be used when the item is ready to evolve. On top of that you can't use a different kind of catalyst than the one actually require and you can't use too many or too few. Catalysts are basically automatic as long as you have enough, all you can do is choose to use them. On the other hand, you CAN accidentally use sells for a premium as a material. Those items are universally horrible as a material, but sell really well in the shop. Don't use them by accident, sell them as soon as you can.
- Q:Does the catalyst affect the chemical reaction rate constant? How does the chemical reaction rate constant change when a positive catalyst is added to a reaction?
- The catalyst will change the rate constant
- Q:The role and significance of chemical catalysts
- To speed up or slow down the chemical reaction is to make the chemical reaction more direct, simple and straightforward to adopt
- Q:Several experiments were carried out using catalysts
- Hydrogen peroxide in the manganese dioxide as a catalyst for decomposition reaction: 2H2O2 == MnO2 == 2H2O + O2 ↑ (laboratory oxygen principle)
- 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?
- There are positive catalyst and anti-catalyst, as well as the amount of catalyst is also related to the rate, not the more the better
- Q:Please make it simple because I need it for school and please give to examples for the second part Thanx :D
- A catalyst is a substance that speeds up the rate of a chemical reaction with itself being chemically unchanged at the end of the reaction. They are useful as they help to lower the minimum amount of energy needed ( also known as activation energy) to start the reaction. Hence, by lowering the activation energy of the reaction, they help to speed up the rate of reaction. For example, in the Haber process for the manufacture of ammonia, the catalyst iron is added to speed up the rate of reaction between hydrogen gas and nitrogen gas. Otherwise, the reaction would have proceeded much more slowly. Another example is the catalyst nickel used in the manufacture of margarine and vanadium (V) oxide for manufacturing sulfuric acid. As catalyst remain chemically unchanged after a reaction, they can be reused again and hence, they are required in minute amounts. An example is the washing powder used in washing clothes, they help to remove food stains by digesting the proteins in food. They can be reused after each reaction and hence, you do not need to add in the whole packet of washing powder but only a few spoonful.
- 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:My chemistry teacher wont tell me because it's in the higher course. And i'm not waiting a whole year to find out. And also, google is being a gimp about it. So thanks a lot if you know, I only have basic chemistry knowledge btw, lumen'ss terms if you can.
- Catalysts facilitate the reaction. They might work in several ways. Here is an example: Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process regenerating the catalyst. The following is a typical reaction scheme, where C represents the catalyst, X and Y are reactants, and Z is the product of the reaction of X and Y: X + C → XC (1) Y + XC → XYC (2) XYC → CZ (3) CZ → C + Z (4) Although the catalyst is consumed by reaction 1, it is subsequently produced by reaction 4, so for the overall reaction: X + Y → Z They might also just increase the surface area, thus speeding up the reaction. Example: Coke looses its fizz over time if left with the cork unscrewed. This is because the HCO3 is released as CO2. If you drop a menthos into the coke, it explodes with CO2, because the methos is full of tiny dents in the surface (thus giving it a massive surface area). (i blatantly copied the first example from the wiki)
