- Q:High school chemistry, catalyst activation energy map
- Catalytic reaction is the reaction of the first reaction with the catalyst or attached to the catalyst to form intermediates, and then further reaction to produce products and catalysts, so the amount of catalyst in theory is the same! The activation of these two processes can be reduced! So there will be two peaks! Can be simplified as a peak!
- Q:Is the catalyst considered a chemical reaction?
- The catalyst is involved in the reaction, but in the reaction process is a step in the effect of its shape has not changed, so that did not participate in the reaction.The role of the catalyst is to reduce the activation energy of the reaction, the original one reaction into two or Multiple reactions, each sub-reaction of the activation energy is very low, the reaction is very good, the effect is the total reaction faster. Hope to adopt
- Q:The best use of chemical catalysts
- Do not know what you want to use the best thing is what the catalyst is generally used in the process, there will be an initial induction period, the catalytic activity is relatively low, and then reached a stable catalytic state, this paragraph is generally called the catalyst life, the final Due to poisoning, active ingredient aggregation and so on factors, the catalyst activity will be reduced, then need to replace the new catalyst
- Q:Chemical reactions in the presence of impurities will cause catalyst poisoning, how to understand this sentence
- Catalyst poisoning reaction of raw materials contained in the trace impurities to the catalyst activity, selectivity significantly decreased or lost phenomenon. The nature of the poisoning phenomenon is a trace of impurities and the catalytic activity of the center of a chemical effect, the formation of non-active species. In the gas-solid heterogeneous catalytic reaction is formed in the adsorption complex. One is that if the toxic and active components of the role of weak, can be a simple way to restore the activity, known as reversible poisoning or temporary poisoning. The other is irreversible poisoning, it is impossible to restore the activity in a simple way. In order to reduce the side reaction activity, it is sometimes necessary to allow the catalyst to be selected for poisoning.
- Q:Are biological enzymes harmful to humans?
- Biological enzymes through scientists more than a century of research, usually known as more than 3,000 kinds of enzymes, the current application of biological enzymes in the textile a wide range of technology, fiber modification, silk degumming, raw hemp (ramie, linen, Kenaf) degumming, dyeing and finishing of the desizing, refining, finishing and net cleaning processing, textile printing and dyeing wastewater treatment and garment processing and other aspects of the application. Enzyme technology has a unique advantage in improving dyeing and finishing processes, saving energy, reducing environmental pollution, improving product quality, adding value and developing new raw materials. At present in the textile processing using a wide range of enzyme preparations are mainly cellulase, protease, amylase, pectinase, lipase, peroxidase, laccase, glucose oxidase eight categories.
- Q:Chemistry why the catalyst can be equal to speed up the positive reaction rate
- Since the catalyst only changes the activation energy and the amount of reactivity can be reduced, the amount of reaction energy is also reduced. Therefore, a positive catalyst is also a good catalyst for its reaction. Speed up the same multiple.
- Q:What is a chemical catalyst?
- A substance that participates in chemical reactions but does not change the quality and chemical properties. It can change the reactant activation energy, speed up or slow down the reaction rate.
- Q:Is the chemical reaction rate constant related to the amount of catalyst used?
- The catalyst has a certain amount of suitable range, the general factory production of some substances (such as ammonia), the amount of catalyst used is limited, to achieve a value after no greater role. So the reaction rate constant is independent of the amount of catalyst used
- 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 definition of a chemical reaction rate in a chemical reaction can be changed (accelerated or slowed down) in a chemical reaction, and the quality and chemical properties of the substance itself are not catalyzed before and after the reaction (which will change during the reaction) Also known as catalyst. Its physical properties may change, for example, MnO2 in the catalytic potassium chlorate to generate potassium chloride and oxygen before and after the reaction from the block into a powder. There is also a saying that the catalyst reacts first with one of the reactants and then the two products continue to undergo a new chemical reaction under the original conditions and the reaction conditions of the catalyst reaction product are more favorable than the reaction conditions of the original reactants Changed.
- Q:When you write a chemical equation, how do you want to add "catalyst" and "?" When you do not have to write?
- This is the need for your memory, write a few times, will naturally cooked
