- Q: On the issue of chemical balance and catalyst
- If the chemical equilibrium does not move, then only the catalyst can change the time to reach equilibrium. If you change the temperature, pressure, it will affect the chemical balance.
- 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: Have you Read it ? If SoCan You Think Of Any Good Group Discussion Questions ?
- yea is an extremely solid e book yet very tragic. there have been no longer any sesquipedalian words( clever and long ) and you are able to desire to get words u mite no longer understand wid counsel from contxt clues. have enjoyable!!
- Q: What is a catalyst in a chemical reaction?
- A catalyst provides an alternative reaction pathway with a lower activation energy. So it speeds up the rate of reaciton because the energy of the particles/reactants doesnt have to be that high to OVERCOME the activation energy so it can therefore react. The activation energy is the minimum amount of energy required for particles to react, so the lower it is, the more faster a rate of reaction will be.
- Q: pls give one or two catalysts that are used in the industry for example:Rhodium catalyst in a catalytic converter of a car or the Iron catalyst for making ammoniaTHANKS :)
- u . s . a . of america has an excellent style of organic gas. In theory that's accessible to have an electric powered motor force a compressor to take the low stress gas to make it dense adequate to get adequate interior the vehicle to run for a mutually as (in actuality, gas stations with organic gas pumps do it precisely like that, that's no longer trucked to them, we've a pair in Dallas) the real undertaking is that, specific it will be pressurized, requiring a greater perfect tank than propane, that's a liquid interior the tank, and the tank must be a cumbersome cylinder for capability or numerous smaller cylinders area by making use of area. Getting this into the physique of the vehicle devoid of doing away with all the storage/bags area isn't ordinary. And ultimate efforts nevertheless finally end up with the miles in line with fill up being decrease than the gas which inserts in a small area.
- Q: In the catalyst and light conditions to break down the water to get the chemical equation of hydrogen
- 2H2O = 2H2 ↑ + O2 ↑
- Q: Will the catalyst in the chemical reaction be reduced?
- The amount of catalyst in the chemical reaction is not reduced, the catalyst is divided into a positive catalyst and a negative catalyst, the positive catalyst promotes the reaction, and the negative catalyst inhibits the reaction
- Q: What is the reaction in chemistry?
- Industrial production of ammonia, ethanol, industrial synthesis of ammonia, ethanol catalytic oxidation, acetaldehyde oxidation into acetic acid, ethyl acetate preparation, the transformation of automobile exhaust, benzene substitution reaction and addition reaction, some other addition reaction of hydrocarbons, Ethanol dehydration to produce ethylene and so on
- 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: Palladium is the main catalyst in chemistry?
- Palladium in the chemical mainly to do the catalyst; palladium and ruthenium, iridium, silver, gold, copper and other alloy, can improve the palladium resistivity, hardness and strength, used in the manufacture of precision resistors, jewelry and so on. While the most common and most commercially available palladium jewelery is palladium.
