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 kind of chemical reaction requires a catalyst?
For example, the system of ammonia, S02 oxidation into SO3
Q:what is a fuel catalyst?
A okorder.com/... Real world test is the sure proof.
Q:What is the maximum impact of the chemical reaction rate?
But the temperature is greater than the concentration of concentration and pressure on the solid and pure liquid is not affected
Q:Is there a catalyst in the chemical shop?
If it is manganese dioxide what is sold because it is not dangerous not expensive
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:What reactions need catalysts?
Reactions that have high Activation Energy need catalysts to speed up reactions. These reactions aren't spontaneous since the reactants do not have enough energy to overcome the activation energy barrier. Catalysts are compounds that speed up reactions by providing an alternative pathway for the reaction. It is a common misconception that catalysts lower the activation energy. It doesn't actually lower the activation energy, instead it provides an alternative pathway with lower activation energy. For example, breakdown of hydrogen peroxide happens in nature but, relatively slowly. When you add a little bit of manganese dioxide, the breakdown happens a lot faster. Another example is, breakdown of glucose in the body. It is facilitated by an enzyme called amylase (or carbohydrase). An industrial example is the use of vanadium pentoxide (V2O5) in the Contact process, where SO2 is converted to SO3 in the presence of V2O5. Hope that helps!
Q:Which of the following are true about catalysts?
(c) rather catalyst varies the path of reaction or u can say mechanism of reaction in which activation potential gets shrink consequently of which fruitful collisions occurred at particularly shrink temperature so better opportunities for molecules to go activation complicated a catalyst is a substance that lowers the activation potential of a chemical reaction yet itself final unchanged during the time of the reaction
Q:What is the role of the catalyst in chemical knowledge?
Positive catalyst is to speed up the negative catalyst to slow down some reaction must be used to the catalyst otherwise difficult to react
Q:reactants are constant or the quality and chemical properties of the catalyst are constant?
The morphology of the catalyst may change before and after the chemical reaction, but the quality and chemical properties of the chemical reaction do not change before and after the chemical reaction. It is noteworthy that this does not mean that the catalyst is not involved in chemical reactions. Some chemical catalysts are involved in chemical reactions, but in the form of intermediates, consume a certain amount of catalyst in a chemical reaction, but in the subsequent chemical reactions, the same quality of the catalyst will be produced. On the whole, the quality of the catalyst before and after the chemical reaction is not changed.
