- Q:why is palladium/platinum a good catalyst?
- Sparky 22 is wrong. Metals like palladium and platinum and nickel do absorb hydrogen. For example many times when doing a catalytic hydrogenation with Raney-Nickel you do not need to add H2 because enough H2 is already absorbed on the metal.
- Q:Comparison of biocatalysts with chemical catalysts!
- biocatalyst activity is adjustable, can be subject to hormones and other active regulation of hormones.
- Q:When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
- No need, because the catalyst in the chemical reaction before and after the quality of the same
- 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: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:Could you please explain it, i know they increase reaction rates but how?
- A catalyst lowers the activation energy (the minimum amount of energy needed for a reaction to take place). This means that the particles can react with less energy than they needed before the catalyst was added. (Think about it: if the government lowered the legal age to buy cigarettes, then more people could legally buy cigarettes. Similarly, if we lower the amount of energy needed for particles to react, then more particles can react). Also, a catalyst provides a surface on which the reaction can take place. This increases the number of collisions between the particles of the substances that are reacting.
- Q:What is the PTC catalyst in chemistry?
- 1, polyether chain polyethylene glycol: H (OCH2CH2) nOH chain polyethylene glycol dialkyl ether: R (OCH2CH2) nOR2, cyclic crown ethers: 18 crown 6,15 crown 5, Fine and so on. 3, quaternary ammonium salt: commonly used quaternary ammonium salt phase transfer catalyst is benzyl triethyl ammonium chloride (TEBA), tetrabutyl ammonium bromide, tetrabutylammonium chloride, tetrabutylammonium hydrogen sulfate (TBAB) , Trioctylmethylammonium chloride, dodecyltrimethylammonium chloride, tetradecyltrimethylammonium chloride, and the like. 4, tertiary amine: R4N X, pyridine, tributylamine and the like. 5, quaternary ammonium base (its alkaline and sodium hydroxide similar) soluble in water, strong hygroscopicity. 6, quaternary phosphonium
- Q:Always speeds the reation ratedoes not affect the reation rateundergoes a chemical changedoes not become part of the chemical changealways slows the reation rate
- Does not become part of the chemical change. I am guessing that this is a multiple guess test and the answer you are looking for is D.
- Q:What is the quality of the catalyst in the chemical reaction, for example, 34.3 g before the hydrogen peroxide reaction, 32.7 g after the reaction, and how much is the catalyst mass?
- You can not calculate this question, the quality of the catalyst before and after the same reaction, how much reaction before the reaction on how much
- Q:The size of △ H in the thermochemical reaction equation is related to the use and unused catalyst
- There is no relationship between the catalyst can only change the reaction rate
