- Q: The addition of the catalyst has no effect on the chemical equilibrium of the movement
- The essence of chemical equilibrium is a dynamic equilibrium. Under certain conditions, the equilibrium constant of the reaction is a certain value. The role of the catalyst is to reduce the activation energy required for the reaction, increase the number of activated molecules, and increase the number of molecules per unit time , But the positive reaction is positive for the reaction, so do not change the speed.
- Q: High school chemistry, catalyst activation energy map
- Catalytic reaction is the reaction of the first reaction with the catalyst or attached to the catalyst to form intermediates, and then further reaction to produce products and catalysts, so the amount of catalyst in theory is the same! The activation of these two processes can be reduced! So there will be two peaks! Can be simplified as a peak!
- Q: What is the nature of the chemical catalyst?
- Catalyst is the chemical reaction can change the reaction rate of other substances, and its own quality and chemical properties in the chemical reaction before and after the material has not changed Some catalyst can really slow down the reaction rate, the book said only refers to the usual circumstances , In general, junior high school and high school teaching into the do not do special instructions are understood to speed up the reaction rate. It is only necessary to know that the catalyst is not only used to speed up the reaction rate. Once the reversible reaction reaches equilibrium, adding the catalyst does not break the balance, but at the same time accelerates the forward and reverse reaction rates. The degree of acceleration is the same.
- Q: What is the difference between biological enzymes and chemical catalysts?
- Biological enzyme is a protein, according to the mild reaction conditions, high specificity, the advantages of strong catalytic capacity,
- Q: Please name 2 common examples of catalysts.Thank you?
- Easter in making Curd fermentation.Sodium bi carbonate in faster flour formation. these are used in the domestic kitchen mostly.
- Q: Is there a catalyst for a chemical reaction?
- There may be many, but some of the catalytic effect of the catalyst is good, and perhaps some of the catalyst has not been found
- Q: give an example of how a catalysts speeds up the rate of reaction?? thank you!!?
- Catalysts speed up a reaction, but at the end of it, it's chemically unchanged. You usually have the same mass at the end of the reaction. For example.. Consider the decomposition of Hydrogen Peroxide: 2H2O2 -2H2O + O2 I hope you got how to represent it =D So.. This reaction is very slow. You can try it out in the lab. So when we add a catalyst, the reaction speeds up. The catalyst used here is MnO2.. Manganese dioxide. Well.. The Enzymes in our body are also Catalysts. They speed up the Biological Reactions taking place inside out body. I hope this answers your question. :) Cheers
- 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 does not participate in the reaction, but play a catalytic role, if the reaction is not called the catalyst
- Q: Will the catalyst decompose during the reaction between two substances? Exp:the decomposition of hydrogen peroxide.Will the manganese 4 oxide decompose?
- Catalysts are not used/destroyed in any reactions, it merely speeds up the process by lowering the reaction activation energy. It functions by being able to weaken or break the required bonds necessary in the chemical reaction (thus lowering activation energy) through temporary and weak bonding to form a complex. In this case the H2O2 molecule will bind with the MnO2 molecule due to the complimentary sites (thus forming a complex) to weaken the bonds for decomposition, but after decomposition the products (oxygen and water molecules) break off from the catalyst (as there are no more complementary sites with them) thus the catalyst will not be destroyed.
- 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.
