- Q: What is positive and negative catalyst in chemistry?
- Positive catalyst can speed up the reaction rate, negative catalyst can slow down the reaction rate
- Q: What are the catalysts that appear in the chemistry experiment?
- Oxygen Oxygen Oxygen Oxygen also used when the catalyst is manganese dioxide MnO2
- 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: 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: What is the difference between an enzyme catalyst in a living body and a catalyst in chemistry?
- Enzyme has a high catalytic efficiency (high efficiency) Generally speaking, the reaction rate of the alcohol catalyzed reaction rate is 106-1013 times higher than that catalyzed by the chemical catalyst
- 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 the nature and quality of the catalyst itself change before and after the chemical reaction?
- Will not change! In fact, the catalyst in the chemical reaction is to participate in the reaction, but in the reaction it not only participate in the reaction, but also generated, and the amount of reaction and the amount of equal, the total amount of the same, this process is more complex, But sometimes the problem will appear, but the information will be very clear, will not affect the problem!
- Q: i keep messing up on those 2 simple things haha i would apprecaite some help.
- enzymes help biochemical reactions proceed at a faster rate than normal in a physiological system, catalysts or sometimes referred to as subunits, metals and other ligands, bind enzymes, and can have a positive and negative effect on the rate of a reaction. search them on wikipedia!
- Q: How to poison the catalyst. What can be done?
- In the reactants or catalyst mixed with a small amount of material, so that the catalyst catalytic capacity of a sharp decline or even loss, this phenomenon is called catalyst poisoning. For example, in the synthesis of ammonia feed gas containing CO, CO2 and H2S, PH3, water vapor and other impurities, can make iron catalyst poisoning; contact with the system of sulfuric acid, if arsenic and selenium oxide (As2O3, SeO2), can make vanadium catalyst Loss of activity. Therefore, it is necessary to purify the feed gas, prevent the poisoning of the catalyst, and also reduce the corrosion of the equipment. The phenomenon of catalyst poisoning is sometimes temporary, the removal of toxicants, the effectiveness of the catalyst can still be restored; sometimes it is permanent, without chemical treatment can not restore catalytic performance.
- Q: An important property of the catalyst is that the reaction equilibrium is not changed while increasing the forward reaction rate and the reverse reaction rate. However, because the enzyme for the specificity of the substrate, is not almost every reaction by the enzyme are one way to do it.
- In biochemical reactions, most appear to be positive / inverse reaction combinations, in fact there are differences in peripheral product / energy offerings. In addition to the molecules of interest, there are many other small molecules involved in the reaction, and these small molecules in the forward or reverse reaction in the transformation is not completely mutually negative. Even for the same reaction, since the corresponding substrate may be removed in the subsequent step and the pulling balance occurs, it is also possible that the forward or reverse direction can occur. Decisive factors usually come from the surrounding other enzymes, coenzymes, small molecules concentration.
