White Carbon Black The Fumed Silica

Q: In the chemical calculation, the quality of the catalyst should not be counted before and after the reaction: Half is not easy to save trouble

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 about the chemical reaction of the catalyst if there is no catalyst?: Slow response or no reaction

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: Does the catalyst slow down the chemical reaction rate? Still can only accelerate: The role of the catalyst is to change the activation energy to achieve the purpose of changing the reaction rate, there is a rate of response to speed up the rate of slow response

Q: explain how a catalyst can affect the rate of reaction but not be in the overall equation.?: Catalysts act to increase the rate of reaction, for example by providing an alternative reaction pathway which lowers the activation energy of the reaction i.e. increasing the likelihood of successful collisions between the reactants. However, they are not used up during the course of the reaction, and at the end you have exactly the same mass of catalyst as you started with, unlike the reactant(s), which will be used up to form product(s). So, the overall equation of the reaction does not include the catalyst because it only needs to show the substances which are used up or formed during the course of the reaction i.e. the reactants and products.

Q: I think doubling the concentration of catalyst will double the rate of a reaction (K2/K1 =2). I want to confirm. This is for my project work. Please reply as soon as possible.: A catalyst speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy, thus increasing the number of collisions that can result in the formation of product. When the catalyst is a reactant in the rate determining step, and the reaction is first order in the catalyst, then a doubling of the concentration will double the rate. But if the rate determining step which includes the catalyst is not first order, then doubling the concentration won't double the rate. Then there is the case of a heterogeneous catalyst in which the reaction is essentially zero order in the catalyst. The amount of catalyst won't affect the speed of the reaction beyond the initial increase. The mere fact that the catalyst is present speeds up the reaction.

Q: The greater the chemical adsorption strength, the catalyst activity changes: If the adsorbent is a reactant, then the better the adsorption capacity of the better catalytic effect; but the catalyst surface of the product will generally have adsorption, if this effect has become very strong, then desorption The process will become difficult, the catalytic effect will decline; the other one, if the adsorption of other substances, such as the reaction may produce a reaction or the catalyst will poison the material, it is greatly detrimental to the catalytic effect. The effect is to be controlled in a suitable optimum range for superior, and preferably to be selectively adsorbed.
