- 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 is metallocene catalyst technology?
- Metallocene catalyst A transition-metal atom sandwiched between ring structures having a well-defined single catalytic site and well-understood molecular structure used to produce uniform polyolefins with unique structures and physical properties. See also Catalysis; Coordination chemistry; Coordination complexes; Metallocenes; Organometallic compound. In the early 1980s, W. Kaminsky discovered that an appropriate co-catalyst activated metallocene compounds of group 4 metals, that is, titanium, zirconium, and hafnium, for alpha-olefin polymerization, attracting industrial interest. This observation led to the synthesis of a great number of metallocene compounds for the production of polymers already made industrially, such as polyethylene and polypropylene, and new materials. Polymers produced with metallocene catalysts represent a small fraction of the entire polyolefin market, but experts agree that such a fraction will increase rapidly in the future. See also Polymer; Polymerization; Polyolefin resins.
- Q:What is the nature of the chemical catalyst?
- Different reactions have different catalysts, mainly catalyzed, to speed up the reaction rate
- 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:how could scientists know the exact catalyst for every reactions??? THANX sooo much
- Believe me, nema, there's no way that we chemists know the best catalyst for every reaction. That would be simply impossible. However, from the type of reaction, the reactants, products, reaction conditions, solvents, etc. and from one's experience and the literature (papers and patents) one can get a good idea for most reactions of the type of catalyst that has worked for similar systems. One then starts off with a catalyst from the literature and modifies or changes it if improvement is needed based on chemical principles that one learns. There are also some theoretical calculations that can be made. Sometimes they work and sometimes they don't :) If it is an industrially important process like the Haber process for making ammonia from nitrogen gas and hydrogen gas, there may be thousands of catalysts which have been tried and evaluated. New minor improvements are being made every day. When a company does find a very good catalyst for an important reaction, often they keep it a trade secret. The good catalyst can make a huge difference in how commercially successful a particular process is. That's a large part of what chemical engineers do. You may never know if you have the best catalyst. The most you can hope for is one that is good enough. So it's a few parts personal knowledge, a few parts literature, a couple of parts theory, a lot of experimentation and often, more than not, a little luck. :)
- Q:What is the similarity between enzymes and general chemical catalysts?
- (1) The enzyme is the same in many respects as a biocatalyst and a general catalyst, such as a small amount and a high catalytic efficiency. As with the general catalyst, the enzyme can only change the rate of chemical reaction and does not change the equilibrium of the chemical reaction It is possible to catalyze the activation of a large number of substrates in a short time and to reflect the high efficiency of enzyme catalysis.The enzyme can reduce the activation energy of the reaction (activation) (△ G) during the reaction, but the reaction rate is accelerated and the reaction time is reduced, but the equilibrium constant is not changed. (2) However, the enzyme is a biological macromolecule (1) Enzyme-catalyzed high efficiency: The catalytic effect of the catalyst can increase the reaction rate by 10 ^ 6 ~ 10 ^ 12 times, which is at least several times higher than that of the conventional catalyst. (2) The enzyme catalyst Highly specificity: including specificity of response, substrate specificity, chirality specificity, geometric specificity, etc., that an enzyme can only act on a certain class or a specific substance. Bond, ester bond, peptide bond and so on can be catalyzed by acid-base hydrolysis, but the hydrolysis of these chemical bonds are different, respectively, the corresponding glycosidase, esterase and peptidase, that is, they were specific (3) enzymatic reaction conditions are mild: enzymatic reaction is generally carried out in aqueous solution of pH = 5 ~ 8, the reaction temperature range is 20 ~ 40 ℃
- 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:What kind of chemical substances can seriously damage the ozone layer, as a catalyst or reactants can be?
- Freon decomposition of free radicals. The destruction of our ozone is mainly caused by him. Chlorine free radicals are also available.
- Q:woulld you be able to answer these aswell i really dont know how to do this cehmestryExplain how, and why, an atom of chlorine (Cl) and an atom of lithium (Li) would form a chemical bond with each other. (iii)Explain what is meant by electronegativity and how it can be used to determine the nature of a chemical bond. (iv)Write a note outlining what is meant by vapor pressure and explain how the concept is used to define the boiling point of a liquid.
- Because of the production of photochemical oxidants from NOx reacting with hydrocarbons in sunlight Noxer blocks are used to rid the NOx from the surroundings through The titanium dioxide (TiO2) on the bocks absorbs ultra-pink radiation from daylight which excites its electrons to a bigger orbital. On the outside of the crystals of TiO2 a reaction happens between oxygen and a high power electron from the TiO2. O2 + e? --O2 ? The excessive vigor electron is then given back to the TiO2 when water then reacts with the oxygen to present H2 O + O2 --H+ + O2 ? + OH Nitrogen dioxide is oxidised to nitrate ions as a result of the hydroxyl radical being an awfully strong oxidising agent NO2 + OH --H+ + NO3 ? The superoxide from response 3 also varieties nitrate ions from nitrogen monoxide. NO + O2 ? --NO3 ? This nitrate is washed away through rain or combines with the concrete within the block.
- Q:Organic chemical concentration of bromine and liquid bromine What is the difference between the conditions in the iron as a catalyst can not be reacted with toluene to produce tribromotoluene? Is it possible to work with phenol to produce tribromophenol?
- The concentrated bromine water is a bromine aqueous solution and the liquid bromine is pure bromine. Only liquid bromine can produce tribromotoluene, and to add iron powder as a catalyst, and the main production is to lead bromotoluene and p-bromotoluene, tribromotoluene this content is very small.
