- Q:Will the chemical catalyst not reduce that?
- Why is it done? Although the catalyst does not react chemically, the catalyst itself is deteriorated and is not always used
- Q:What is the principle of the catalyst? Why can change the rate of chemical reactions and their own without any change
- If you are not asking for a written, you can look at my words. The principle of the catalyst is to make the water muddy. It has to accelerate the chemical reaction, but also slow down the reaction. Catalyst ions into the solution, is to let the solution become muddy, and then should be the reaction of the ion collision probability is large, to speed up the reaction. The substance of the catalyst does not participate in the reaction, so it does not change. Are personal understanding, wrong please more inclusive. Thank you
- Q:How does active charcoal catalyze in some chemical reactions?
- Generally not, but it can be used as a catalyst carrier
- 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:Could you tell me all the differences between those two catalysts? Thank you very much.
- Biochemical Catalyst
- Q:Can the catalyst be a reactant in chemistry?
- In the chemical reaction can change the chemical reaction rate of other substances (both improve and reduce), and its own quality and chemical properties in the chemical reaction before and after the material did not change called catalyst. [From the definition of reactants. To
- Q:Does all chemical reactions have a catalyst?
- Not some reaction without catalyst
- Q:The size of △ H in the thermochemical reaction equation is related to the use and unused catalyst
- There is no relationship between the catalyst can only change the reaction rate
- Q:The role of catalyst in chemical reactions
- Negative catalysts can be used to control the reaction rate (such as some reaction too fast, instantly release a lot of energy caused by danger, you can join), common is the antioxidant
- 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?
- Catalyst before and after the reaction of the same quality,
