- Q:What is a catalyst in a chemical reaction?
- A catalyst is a compound in chemistry (it can be an acid or temperature or a base or a metal or anything, pressure anything) that shifts the reaction towards one product or the other... In simple words. If you want to obtain something, e.g. water, then you can obtain it in different timings, ie in 2000 years, but if you want to obtain it in 2 hours instead of 2000 years then you add a catalyst, e.g. you heat the reaction to speed it up, you add an acid, or a base etc. Some catalysts also act on the regioselectivity of a compound thru preferring the formation of a stereo-isomer to another. E.g. if you want to obtain S-Thalidomide instead of R-Thalidomide you use a particular catalyst etc...
- Q:Is it not the rate to accelerate the addition of the catalyst to the catalyst, and that is why the balance does not move
- If the reaction before the catalyst, you can speed up the reaction rate, that is to achieve the balance required to reduce the time, but to balance the system when the same concentration
- Q:The addition of the catalyst has no effect on the chemical equilibrium of the movement
- Hello, the essence of chemical equilibrium is a dynamic equilibrium, under certain conditions, the equilibrium constant of the reaction is a certain value, the role of the catalyst is to reduce the activation energy required for the reaction, increase the number of activated molecules, so that the reaction within a unit time The number of molecules increased, but the positive reaction is positive for the reaction, so do not change the speed
- Q:What is the standard for the storage of flammable and explosive chemicals now?
- First, the basic requirements of classification of storage Dangerous goods, variety, complex performance, storage, in accordance with the zoning, classification, sub-section of the principle of special storage, set the number, set the number of fixed warehouses, fixed staff (four) custody. Small warehouses should be classified, divided, sub-stack storage, the performance of each other, fire fighting different items, dangerous dangerous goods and other general dangerous goods, should be stored separately.
- Q:What are the pharmaceutical manufacturing companies now using PT / AL_203 catalysts?
- Yueyang Eagle Hill Petrochemical Plant
- Q:Is the chemical reaction rate constant related to the amount of catalyst used?
- The decomposition of hydrogen peroxide, manganese dioxide in addition to the catalyst, but also in which it can be considered a carrier (from the surface of manganese dioxide to emit small bubbles, you should be able to see), so the amount of more than certainly can speed up the reaction.
- Q:Can chemical reaction limits be changed by catalyst or other methods?
- No, the catalyst can only speed up the chemical reaction, but can not change the chemical limit.
- Q:Cl + O3 ---> ClO + O2O + ClO ---> Cl + O2= O + O3 ----> 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:Could God be Discribed as a Catalyst?
- It depends on the context. A catalyst for what? A catalyst being (from a scientific point of view anyway) something that speeds up the rate [of a reaction] without itself being altered. In that respect you could view God as being a catalyst for war, or religious hatred. The counter argument being that it is religion (ie. the interpretaion of God) which is the catalyst. And not to be too negative, God could be seen as a catalyst for good; many of the charitable organisations in the world are theistic in some way. Point is, I'd say that religion, rather than God himself, is the driving force. I don't believe in God, but I ain't, like, zealous about it.
- Q:Describe the role of a catalyst and a substrate in a chemical reaction.
- a catalyst lowers the activation energy of a reaction. By lowering the activation energy, the internal kinetic energy the reactants become sufficient for the reaction to occur on a much larger scale and thus appear faster. Without the catalyst, you would depend on the statistical probabilities of small numbers of reactant particles having enough internal kinetic energy to overcome the activation barrier. a substrate is merely the substance in the reaction being catalyzed
