- 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: 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: Chemical master invited (about catalyst)
- From the thermodynamics can be reaction, and the three formulas can be added to eliminate the intermediate product, indicating that the reaction may occur. The definition of the catalyst is not complete. I am a junior undergraduate student of Jilin University School of Chemistry, according to the definition of the catalyst in the university textbook, the catalyst itself reacts with the reactants to produce unstable intermediates. After the reaction is finished, the intermediate product is explained and the catalyst is reduced. Apparently did not participate in the reaction. So the catalyst to change the course of the reaction, the original reactants to go through a relatively high energy to produce products, there will be a catalyst after a few relatively low energy barrier, so much easier, the reaction rate is greatly accelerated The It can be seen, the catalyst is not no response, but only after the completion of the reaction to restore it. It can also be seen that the amount of catalyst does not matter, and some reactions require the amount of catalyst to be approximately equal to the amount of reactants. Waiting for you to high school and university to further study on this issue will have a more clear understanding of the.
- Q: What makes an enzyme a catalyst?
- A catalyst is a substance that speeds up a chemical reaction, by lowering the activation energy, and which is not consumed or permanently altered in the process (such that after it has catalyzed the reaction once, it can catalyze the reaction again, and again -- multiple turnover). Catalysts can be as simple as a monatomic ion; they can also be inorganic compounds, non-biological organic molecules, or biological molecules. Biological catalysts are enzymes. Enzymes meet all of the criteria for being a catalyst (speed up chemical reactions, by reducing the activation energy, and are not permanently altered).
- Q: Please name 2 common examples of catalysts.Thank you?
- Well, there's Adam's Catalyst (PtO2) which is one of the most used catalysts.
- Q: Is it not the rate to accelerate the addition of the catalyst to the catalyst, and that is why the balance does not move
- In the chemical equilibrium, after adding the catalyst, the positive and negative reaction rate increases equally, but the positive reaction rate is still equal to the reverse reaction rate, so the balance does not move
- Q: If the college entrance examination questions related to whether the catalyst involved in the reaction, how should I answer. (We must college entrance examination, I hope you help out, thank you.)
- The catalyst was involved in the reaction, but the physical and chemical properties did not change before and after the reaction.
- Q: role of catalyst?
- Catalysts are used to increase the rate of chemical reactions.
- Q: What kind of chemical reaction requires a catalyst?
- Too much reaction, and basically related to the industry
- 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.
