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: 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: 1. Catalysts can help to bring the reactants together in the correct orientation2. The chemical formula of a catalyst is written on the left hand side (reactant) side of an equation.3. Catalysts can provide a surface on which the reaction occurs.4. Catalysts increase the activation energy.5. Catalysts increase the magnitude of the equilibrium constant, thus favoring product formation.6. &quot;Enzymes&quot; are biochemical catalysts.7. Catalysts increase the rate of a reaction.8. Catalysts are slowly used up during the reaction and need to be replaced.: 1. Catalysts can help to bring the reactants together in the correct orientation False. It provides an alternative pathway (of lower activation energy) for reaction to occur. 2. The chemical formula of a catalyst is written on the left hand side (reactant) side of an equation. False. Written on the arrow that show the reatctants becoming products. 3. Catalysts can provide a surface on which the reaction occurs. True. For instance platinium in the case of hydrogenation of alkenes.

Q: CO and NO react under the action of a catalyst to generate chemical formulas for CO2 and N2.: N from +2 to 0 price 2e * 2

Q: Brief introduction of enzyme as biocatalyst and general chemical catalyst and its personality: can only change the rate of chemical reaction, do not change the equilibrium point of the chemical reaction, the enzyme itself does not change before and after the chemical reaction (3) can reduce the chemical reaction of the activation energy The

Q: Explain how catalysts help to reduce costs in industrial processes !?Thanks: Catalysts are efficient at converting starting materials to the final products. Since catalysts convert these materials to the product faster, less energy will be used, and often less other materials will be used to complete the process. Both will save the company save time and money. Not to mention the catalyst can be reused, often hundreds of times before it needs to be replaced. Hope that helps!

Q: I have just spent CAN$550 to replace a catalyst converter at one end of the muffler. The repairman said I need to replace the oxygen sensor very soon, otherwise, the C.C. will be gone again. Is that true... can someone confirm this for me. Thanks.: ok its not catalyst converter its catalytic converter. next i have not read one answer that is correct a couple are close but no cigar. ok the 02 sensor senses the oxygen content in the exhaust gasses. using the oxygen content it can determine if the engine is running to rich or to lean. the ecm (computer) wants to keep the engine at optimum fuel mileage or keep it stoichometric meaning fuel to air ratio of 14.7:1 the ecm can adjust fuel air ratios by changing the pulse width and the duty cycle or on off time of the injector.it also uses several other sensors to help it like intake air temp (iat) coolant temp (cts) mass air readings if equipped (MAF) or manifold absolute pressure (map) so its not just the oxygen sensor it can make adjustments as need. anyways the oxygen sensor uses a .1 to .9 volt range signal anything below .450 is lean anything above .450 is rich and .4 to .5 is perfect. but ur engine constantly changes and the 02 readings change constantly new cars can take readings as fast as one or two times a second older cars are alittle slower. anyways only replace the 02 sensor if the car is telling u its bad meaning u have a check engine light on and a code that says P 0 . . . bank one sensor one ckt malfunction or bank 2 sensor 1 ckt malfunction u get the idea unless that happens ur 02's are good leave them alone. when they do go bad ur car will run rich and puke alittle black smoke out the exhaust and ur car will smell like rotten eggs. NOW the cat its job is to heat up to 600 + degreees F and burn unburnt fuel from the combustion cycle of the engine when an engine does not burn all its fuel its running rich and bad fuel milage occurs. if the 02 sensor goes out it can heat the cat red hot as the extra fuel being burnt inside it can become extremely hot. most 02 sensor for most vehicles run around 60 bucks not expensive. a car can have 1 to 4 of these and YES if bad and left for too long and can ruin a cat converter.

Q: Is the enzyme in the enzyme bigger than gold?: No: A biological enzyme is a biocatalyst that is produced or extracted from a biological organism. The catalyst is a substance that accelerates the chemical reaction and does not change itself in the chemical reaction. In layman's terms, the catalyst is a special substance that catalyzes it. Enzyme as a member of the catalyst family has its own special properties. Each of the biological enzymes will only selectively react to some chemical reactions.

Q: If possible can anyone give me information on the active site, substrates, products, and the energy of activation as part of the answer?Responses greatly appreciated! Thankss! 10pts to best answer!: To make it simple unlike the dude above me...enzymes (biological catalysts) lower the activation energy, which speeds up the reaction. EVERY reaction needs a little boost of energy--the activation energy--and enzymes lower that.

Q: Can you describe at least 4 ways a catalyst can lower the activation energy of a reaction?: To see how a catalyst accelerates the reaction, we need to look at the potential energy diagram shown below which compares the non-catalytic and the catalytic reaction. For the non-catalytic reaction, the figure is simply the familiar way to visualize the Arrhenius equation: the reaction proceeds when A and B collide with succificient energy to overcome the activation barrier. The change in Gibbs free energy between reactants, A + B, and the product P is delta G. The catalytic reaction starts by bonding of the reactants A and B to the catalyst, in a spontaneous reaction. Hence, the formation of this complex is exothermic and the free energy is lowered. There then follows the reaction between A and B while they are bound to the catalyst. This step is associated with an activation energy; however, it is significantly lower than that for the uncatalyzed reaction. Finally, the product P seperates from the catalyst in an endothermic step. The energy diagram illustrates 4 ways the catalyst works : The catalyst offers an alternative path for the reaction that is energetically more favorable The activation energy of the catalytic reaction is significantly smaller than that of the uncatalyzed reaction; hence the rate of the catalytic reaction is much larger The overall change in free energy for the catalytic reaction equals that of the uncatalyzed reaction. Hence, the catalyst does not affect the equilibrium constant for the overall reaction. A catalyst cannot change the thermodynamics of a reaction but it can change the kinetics. The catalyst accelerates both the forward and the reverse reaction to the same extent. In other words, if a catalyst accelerates the formation of product P from A and B, it will do the same for the decomposition of P into A and B.
