- Q: What is the superiority of the catalyst compared to the stoichiometric reagent?
- Some enzymes are related to cofactors, and because of the fact that most enzymes are proteins, they are destroyed by high temperatures, strong acids and strong bases.
- Q: What is catalyst in Science?
- A catalyst is a substance that aids a chemical reaction (by doing this increasing the reaction rate) but is not consumed by the reaction. For example, hydrogen peroxide (H2O2) spontaneously decomposes into water and oxygen over time. the addition of manganese dioxide will greatly increase the rate of reaction, but none is consumed.
- Q: And hydrogen peroxide
- Can not. They will react
- Q: What is the catalyst for ethylene addition water? How to play a catalytic role.
- With dilute sulfuric acid can be. Sulfuric acid will be added with the addition of ethyl hydrogen sulfide, and then hydrolyzed into ethanol.
- Q: What is the definition and function of the catalyst in chemistry?
- The catalyst plays an important role in chemical production. For example: in the oil refining process, the use of high-performance catalyst into gasoline and no other; in the car exhaust treatment process, with the catalyst to promote harmful gas conversion ...
- Q: Can manganese dioxide be used as a catalyst for various chemical reactions?
- Catalyst in the reaction process involved in the reaction, after the completion of the reaction was reduced to the original ingredients.For example: heating decomposition of potassium permanganate when added potassium permanganate potassium potassium permanganate decomposition process, the potassium permanganate is involved in the reaction, The specific way is not clear.Finally, the occurrence of potassium permanganate before and after the reaction of the catalyst changes in morphology, particles into powder, powder particles and so on.
- 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
- A catalyst works by providing the optimal conditions for a reaction to occur, so the more there is, the more contact it has with the reactant/s, so the more there is, the faster the reaction will take place, until there is a point where there are too many catalyst sites for the number of reactant molecules, so it doesn't speed it up any further past that point, if it's a relatively slow reaction it may slow the process by diluting the solution too much with useless catalyst sites, but generally the reaction rate will reach a point where it will not become any faster, and stay at that maximum speed. less catalyst does mean less speed though, as the catalyst sites have more work to do. hope this helps.
- Q: Just something I've always wondered about...
- activation energy has got nothing to do with this. the main reason that the transition metal oxides are catalysts is that they have vacant d orbitals. the reagents are adsorbed on the metal surface and the d orbitals serve as a sort of clamp between the substrates and reagents. for example if you consider the hydrogenation of ethylene in palladium catalyst here the d orbitals lead to syn addition of hydrogen by clamping the pi electron cloud . this is a sort of chemisorption.
- 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
- In the chemical equilibrium, after adding the catalyst, the positive and negative reaction rate increases equally, but the positive reaction rate is still equal to the reverse reaction rate, so the balance does not move
- Q: Write a chemical formula in a chemical laboratory without the use of a catalyst for oxygen
- 2KMnO4 = K2MnO4 + MnO2 + O2 ↑ ~ conditions are heating
