- 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: Like biological and industrial reations. Thanks.
- 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: Also, how is the catalyst affected by heat? Please answer all of the questions not just one of the three. THANK YOU!
- It denatures the catalyst because the rise in pH or amount of H3O+ ions. Temperature will also denature the catalyst if it's out of its optimum range.
- Q: what is a catalyst ?
- OK- First about what a catalyst does. All reactions require some amount of energy to proceed. For most of of these it is not much and it comes from the reactions immediate environment and we don't notice it. This energy needed is called an energy threshold. Many, if not all, reactions can have their thresholds lowered by something else-platinum-nickle in the cars catalytic converter does this. Catalysts are not used in the reaction so the catalyst, once added, stays there and continues working. By the way, in biology we have organic catalysts (the enzymes).
- Q: How are a catalyst and an intermediate similar? How are they different?
- A catalyst speeds up the rate of a reaction by lowering the activation energy barrier which is, presumably, the energy required to achieve the reaction intermediate. Catalysts are also not consumed in the reaction, they are regenerated towards the end. A reaction intermediate is a configuration that a molecule takes prior to achieving it's lowest energy form which would signify the end of the reaction. Intermediate usually are hard to isolate because of the incentive to go to the most stable configuration. How are they different? A catalyst is not a part of the reaction product and it doesn't get consumed. An intermediate in a reaction is transformed into the product. How are they similar? Well, catalysts drive the reaction and make it easier for the reaction for follow through. Since intermediates are high energy and thermodynamics tells us that low energy is favorable, the incentive for a high energy intermediate to drive down to it's stable for can also drive a reaction. I hope that helps. I hope it makes sense.
- Q: I was hoping to buy a land rover lr4 or lr2, but with the lr4 having gas mileage in the mid teens, i wanted to know if there is a way to improve it. I dont drive on the highway too much. I'd like to know if there is anything else to improve mileage too. I drive a lot of people around for functions, family, and others and I looked at other suvs but those two looked the best.
- Fuel Catalyst
- Q: Hydrogen and nitrogen in the high temperature and pressure and catalyst conditions for the synthesis of ammonia chemical equation
- 3H2 + N2 = 2NH3 conditional catalyst
- Q: In the chemical reaction will have to use the catalyst reaction, such as H2O2 === (MnO2) H2O + O2 ↑, then the catalyst in the end to participate in the reaction (that is, the catalyst itself is the reactant) If so, why are some of these substances in the reaction (these substances refer to the catalyst) in the reaction after the quality and nature of the change does not change?
- The composition, chemical properties and quality of the catalyst itself do not change before and after the reaction; its relationship with the reaction system is as highly selective (or specific) as the relationship between the lock and the key. A catalyst does not catalyze all chemical reactions. For example, manganese dioxide catalyzes the thermal decomposition of potassium chlorate, accelerates the reaction rate, but does not necessarily have a catalytic effect on other chemical reactions. Some chemical reactions are not only the only catalyst, such as potassium chlorate can be thermally decomposed to catalyze the presence of magnesium oxide, iron oxide and copper oxide and so on.
- Q: i keep messing up on those 2 simple things haha i would apprecaite some help.
- A catalyst is a substance that affects the rate of a reaction. It may participate, but cannot be consumed in the reaction. For example, KMnO4 catalyzes the breakdown of H2O2 into H2O and O2. In the end, as much KMnO4 exists as did in the beginning. An enzyme is a biochemical reagent that allows an organism to convert a compound into other compounds. This is part of metabolic processes. For example, maltose (a sugar composed of a chain of two glucose molecules) can be broken down into glucose by the maltase enzyme. Unlike a catalyst, enzymes may or may not be consumed/altered in the metabolic processes.
- Q: Chemistry: Does the catalyst participate in the reaction?
- The catalyst does not participate in the reaction, except that the reaction rate is changed.
