- 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?
- The quality of the catalyst before and after the reaction
- 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: How does catalyst aid a chemical reaction?
- A catalyst works by providing an alternative reaction pathway to the reaction product. The rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst. Catalysts generally react with one or more reactants to form an intermediate that subsequently give the final reaction product, in the process regenerating the catalyst. The following is a typical reaction scheme, where C represents the catalyst, X and Y are reactants, and Z is the product of the reaction of X and Y: X + C → XC (1) Y + XC → XYC (2) XYC → CZ (3) CZ → C + Z (4) Although the catalyst is consumed by reaction 1, it is subsequently produced by reaction 4, so for the overall reaction: X + Y → Z As a catalyst is regenerated in a reaction, often only small amounts are needed to increase the rate of the reaction.
- Q: Why the catalyst is required to have a large surface area and a rich pore structure
- Chemical reactions are generally contact reaction, of course, the more contact with the faster response, pore structure is to increase the contact area
- Q: Explain how a catalyst may increase the rate of chemical reaction?
- A catalyst lowers the acitvation energy of a reaction.
- Q: Please help me
- catalyst are enzymes that increase the rate of a reaction. they both are proteins. so basically, a catalyst is an enzyme that increases the rate of a reaction.
- Q: the process of which the heterogeneous catalyst work in vehicles. a step by step instruction in how they work. :)
- The Reduction Catalyst The reduction catalyst is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the NOx emissions. When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. For example: 2NO =N2 + O2 or 2NO2 =N2 + 2O2 The Oxidization Catalyst The oxidation catalyst is the second stage of the catalytic converter. It reduces the unburned hydrocarbons and carbon monoxide by burning (oxidizing) them over a platinum and palladium catalyst. This catalyst aids the reaction of the CO and hydrocarbons with the remaining oxygen in the exhaust gas. For example: 2CO + O2 =2CO2
- Q: What is the difference between biological and chemical catalysts?
- catalysts which catalyze the chemical reactions taking place in human body such as enzymes are called bio-catalyst and other one's which are generally used in laboratory by chemists for multiple type of reactions are chemical ctalysts
- 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.
