- Q: Why the amount of catalyst is too small will make the chemical reaction rate slowed down
- The catalyst changes the reaction rate by changing the reaction pathway and reducing the activation energy of the reaction.
- Q: Chemistry teaching and learning a bit difficult, thank you
- 2NO + 2CO = 2CO2 + N2
- Q: What are the chemical reaction conditions in organic chemistry are catalyst and heating, please elaborate
- This really does not have omnipotent law, their own more than one point, you can classify to remember, when I was in high school is in accordance with the notes, such as poly, polycondensation and the like. In general, the double triple bond addition, plus halogen is not the conditions, plus HCl, HBr and the like to heat; dehydration reaction generally concentrated H2SO4 heating, dehydration condensation is also; there are some special, such as ethylene added to ethanol Special temperature requirements, it seems that 120 degrees, there are other; other addition poly, polycondensation some need catalyst. The The In short, the conditions are many, in general, you do not go to the high school to do more questions after the feeling, encounter problems do not panic general experience can come out according to experience, this also depends on the usual accumulation, if the equation conditions Wrong to deduct points, it is not worthwhile. There are some questions when the examination will give you some information, whether you know do not know should see clearly, although some of the reaction but the subject to the conditions are not the same, when you do according to the title to write conditions, this will not wrong. In addition, thank you for your help, I do not seem to know you
- Q: What is the catalyst condition in the chemical equation?
- I studied three methods ~ word which can be used to give me a mailbox to the word text to pass you ~
- Q: Could you please explain it, i know they increase reaction rates but how?
- A catalyst provides an alternative route for the reaction, (maybe more steps than previously), but each step having a lower activation energy than the original uncatalysed reaction. This means that although there will be the same number of collisions per second (if the reaction is performed at the same temperature as before), a greater fraction of those collisions will result in a reaction - so there will be more reactions per second. In the case of a heterogeneous catalyst - e.g. a solid surface the change is that the first step is a bond to the surface which waekens some of the bonds in the reactants - again making a greater fraction of reactions result in reaction.
- Q: What is the difference between electrocatalysis and general chemical catalysis?
- General chemical catalysis is a catalyst, and electrocatalysis also need to be carried out under the conditions of the electric field
- Q: explain how a catalyst can affect the rate of reaction but not be in the overall equation.?
- a catalyst is a substance that speeds up the rate of reactions that would already happen (the reactions are spontaneous) but would take a long long time to occur. Every reaction proceeds from a level of high energy to a lower level of energy, but in order to start going downhill you need to get up, in affect getting more energy than the reactants have now. This is because the transition state, or what the reactnat/product is in the middle of the reaction, is less stable and requires more energy than the reactants. Catalysts lower the extra energy needed (called activation energy) to a level that the reactants already have, and the reaction occurs.
- Q: Horseradish enzyme catalyzed Luminol chemiluminescence reaction
- Disinfectant ah ~ bleach ah ~ ~ take this kind of thing to wash the blood once something can interfere with Lumino identification. So that want to do bad things must be a good plan. Lumino in the presence of copper, copper alloy, horseradish or some bleach in the presence of fluorescence. So if the scene of the crime was bleached
- Q: Will the catalyst in the chemical reaction be reduced?
- The amount of catalyst in the chemical reaction is not reduced, the catalyst is divided into a positive catalyst and a negative catalyst, the positive catalyst promotes the reaction, and the negative catalyst inhibits the reaction
- Q: Describe the role of a catalyst and a substrate in a chemical reaction.
- a catalyst speeds up the reaction
