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:What is the reaction of hydrogen peroxide to add manganese dioxide?: There are bubbles produced

Q:explain how a catalyst can affect the rate of reaction but not be in the overall equation.?: Simply, the catalyst provides a better way for the reaction to occur (some won't work without the catalyst) and usually a favorable reaction will run faster if there is a catalyst. There are many ways for this to happen. The catalyst can provide more surface area for a reaction to occur, it can do an adsorption process where one of the reactants sticks to the surface and exposes a portion of the molecule which is more favorable to the reaction. It can lower the energy required for the reaction to occur (same effect as increasing temperature) by favoring an intermediate step in the reaction. Lots of different ways, some not fuly identified or understood. The catalyst people who work with the platinum metals groups are notorious for keeping their mixtures secret. A better gasoline catalyst for refineries is worth billions in profits. It is not considered in the equation because you get back what you start with even if one of the intermediate steps involves changing the chemical composition of the catalyst and then has it returning to its original state with the formation of the product.

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:The quality and nature of the catalyst before and after the chemical reaction did not change this sentence wrong? Why did the "middle school student study" say it was wrong?: The quality and nature of the catalyst are not changed before and after the chemical reaction ... 7604

Q:Does a catalyst work for both reactants and products?From my understanding, organic catalyst or enzyme does not necessarily work for the product of the reaction because of the shape of the activation site. However I cannot speak for inorganic ones.: Generally, catalysts participate and facilitate a reaction, but the catalyst is returned unchanged. For example, sulfuric acid may be used in a Fischer esterification, palladium in a Heck reaction, pyridine in an acylation reaction, hydroxide in an aldol condensation, cyanide in a benzoin condensation, etc. An enzyme can facilitate a reaction is a similar manner, by being an acid or base catalyst for example. We could say that generally, reactions are reversible. Practically, that is not true as the energy differences of the reactants and products may be so different to prevent the reverse, an explosion for example. If a reaction is reversible, that may not mean the reverse reaction will take place. Le Chatelier's Principle can apply to determine the products.

Q:Please name 2 common examples of catalysts.Thank you?: Common Catalysts

Q:Before and after the chemical reaction, the nature of the catalyst unchanged this statement right? Why?: Chemical properties do not change better. Some properties of the catalyst may change before and after the reaction. If the experiment proves, the state of the catalyst before and after the reaction changes, and some changes from powder to powder.

Q:The catalyst before and after the reaction of the quality and nature of the same, does it mean that a little catalyst can be all the substrate reaction? Such as: one gram of MnO2 can reflect the infinite H2O2?: There are positive catalyst and anti-catalyst, as well as the amount of catalyst is also related to the rate, not the more the better

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
