Q:In the chemical reaction, why can the catalyst speed up the reaction rate
Manganese dioxide, copper sulfate, catalytic hydrogen peroxide decomposition.
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.
Q:What progress has chemistry brought to our life?
Q:Effect of Catalyst on Chemical Reaction Rate
The catalyst can reduce the activation energy of the chemical reaction and allow the reaction to take a shortcut
Q:No one knows the expression of the catalyst and the chemical expression of the acridine
In organic reactions, the catalyst is complex and consists of several or more. Write Chinese characters directly.
Q:catalyst and reagents ???
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:how a catalyst can provide a new route in forming the product?
A catalyst will almost always provide an alternative route for the reaction in question. It is common to hear the statement that a catalyst does not take part in a reaction, but that is almost always untrue. Properly defined, a catalyst is a species that alters the rate of a chemical reaction and which can be recovered unchanged BY MASS at the conclusion. In other words, the amount of catalyst present at the end of the reaction is the same as the amount at the start, but the catalyst itself has likely reacted many many times as the reaction proceeded. A simple example is the decomposition of hydrogen peroxide. The reaction taking place can be summarised as: 2 H2O2(l) ---2 H2O(l) + O2(g) This reaction is very slow under normal circumstances. However, if you drop in a crystal of potassium iodide, the reaction becomes extremely fast. The reason is that the potassium iodide dissolves and dissociates releasing iodide ions. These provide a new two-step reaction pathway in which both steps are rapid: H2O2 + I- ---H2O + IO- H2O2 + IO- ---H2O + O2 + I- Notice that if you add these equations together you get the same overall reaction as before. The iodide ion does not take part in the overall reaction, and so must be present at the end. However, it does take part in the mechanism of the reaction, and is undergoing a lot of reactions.
Q:High school stage which organic chemical reactions do not use catalyst
Aldehyde and silver ammonia solution reaction, and the new system of Cu (OH) 2 reaction.
Q:PT / AL_203 catalyst and the main chemical use
Yueyang Eagle Hill Petrochemical Plant
Q:High school stage chemical catalyst
High school is the most common is manganese dioxide, and potassium permanganate heating oxygen, hydrogen peroxide decomposition are used, which is inferred in the problem there is a lot of
