Suggest for Use:

(1)uses for the tire ply, sidewall and the pressure out, calendered products rubber compound.
(2)The usage and to the FDA for natural rubber and various synthetic rubber, easily dispersed, can give quite a high of rubber, extrusion speed, pressure the surface is smooth, mouth-type expansion is small, vulcanized rubber high temperature performance and excellent thermal conductivity, reinforcement, flexibility, and better resilience. Mainly used in tire cord layer, sidewall and the pressure out, calendered products rubber compound. This product is best for the butyl rubber inner tube and used with the N660.

Q: Chemistry is often said that the catalyst can change the material reaction rate, rate and speed What is the difference: The rate is related to the concentration of matter, the velocity is physically, is the vector, has the direction

Q: Cl + O3 ---&gt; ClO + O2O + ClO ---&gt; Cl + O2= O + O3 ----&gt; 2O2What is the catalyst? The intermediate?How do you know which is which? If the rate law is rate=k [O3] [Cl]determine:a) the overall order.b) unit for k.c) the rate determining step, justify your answer.: Cl is the catalyst. ClO the intermediate. The catalyst is the component which does not change in overall reaction. He forms some intermediate component(s) with the reactants. In the later reaction steps the intermediate(s) react forming the catalyst in its original state. (a) The overall order is the sum of the orders with respect to the components: n = 1 +1 = 2 (b) the unit of the rate of reaction is r [=] mol/ (Ls) (more general mol per unit time and volume) compare dimensions mol / (Ls) [=] k · mo/L · mol/L =k [=] L/(s mol) (more general unit volume per unit time and mole) (c) First reaction For elementary reaction steps the order of the reaction rate with respect to a reactant is equal to stoichiometric coefficient. Hence the rate of first reaction is: r? = k?·[Cl]·[O?] Overall rate is given by the rate determining step, while other reaction steps are in equilibrium: r = r? = k?·[Cl]·[O?] If second reaction is the rate determine step r? = k?·[O]·[ClO] while reaction 1 is at equilibrium K? = ( [ClO]·[O?] ) / ( [Cl]·[O?] ) =[ClO] = K?·( [Cl]·[O?] ) / [O?] the overall rate would be: r = r? = k?·[O]·[ClO] = K?·k?·[O]·[Cl]·[O?] / [O?] = k·[O]·[Cl]·[O?] / [O?] That doesn't match the observed rate law

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 a catalyst and an oxidizing agent?: A catalyst alters the rate of a reaction without being used up in the reaction. An oxidising agent oxidises other compounds, the agent itself being reduced in the process.

Q: Chemical "catalyst can speed up the chemical reaction rate of other substances," this sentence right?: Wrong, the catalyst is divided into two kinds, one is to speed up the chemical reaction speed, and the other is the opposite

Q: Will the catalyst be able to increase the rate of chemical reactions?: Not necessarily

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: how a catalyst can provide a new route in forming the product?: a catalyst does not provide a new route. it just lowers something called the energy of activation of the reaction. this makes some changes in the thermodynamics and kinetics of the reaction

Q: Is the enzyme in the enzyme bigger than gold?: A biological enzyme is equivalent to a key that opens a complex compound whose importance is that its unique structure or multidimensional shape matches a part of the group. Once these two parts are combined, the specific chemical bond in the group molecule changes as if the lock was opened. When the reaction is completed, the enzyme is released and repeated with the next group, followed by repeated repeats. Many chemical reactions in the normal temperature conditions, the reaction is very slow so that the whole process is difficult to be perceived.
