Q:what is a catalyst ?
A substance which initiate the rate of chemical reaction without undergoing any change by itself till the end of the reaction.
Q:What are the characteristics of the catalyst in the chemical reaction?
In simple terms: the catalyst itself is involved in the reaction, the quality of the reaction before and after the same, the ingredients do not change. The catalyst can change the rate of chemical reaction, increase the rate of reaction called catalyst, slow the inhibitor.
Q:Chemistry: Does the catalyst participate in the reaction?
The current theory is generally believed that the catalyst to participate in the reaction, the formation of intermediates, and then re-decomposition of intermediates to generate the catalyst, so the quality and nature of the reaction before and after the same. Experiments have shown that although the nature and quality of the catalyst remain unchanged, some of its aspects, such as morphological changes, before the reaction of massive, post-reaction powder, indirectly prove the above theory. Now high school to do the problem generally according to the theory. Such as copper oxidation of copper oxide, copper oxide and then oxidation of ethanol to acetaldehyde, itself is reduced to copper, so copper is ethanol oxidation of acetaldehyde catalyst
Q:In chemistry what is a catalyst and an example?
Catalysts are substances that increase the rate of a reaction by providing a low energy shortcut from reactants to products. In some cases, reactions occur so slowly that without a catalyst, they are of little value. Nearly all reactions that occur in living cells require catalysts called enzymes- without them, life would be impossible. There are two important classes of catalysts: homogenous catalysts like enzymes and aqueous ions that are uniformly mixed with the reactants, and heterogeneous catalysts that provide a surface that holds and reconfigures the reactants in a way that is favorable for reaction. Examples of homogeneous catalysis. Catalysts in solution with the reactants usually provide fast reaction paths by allowing reactants to form an unstable intermediate that quickly decomposes into products. For example, the substitution reaction CH3CH2OH(g) + HCl(g) H2SO4 ----->CH3CH2Cl + H2O(ell) is catalyzed by acid because the ethanol is converted into unstable CH3CH2OH2+, which quickly reacts with Cl- to produce the products. Definition: A catalyst is a subtance that increases the rate of a chemical reaction by reducing the activation energy, but which is left unchanged by the reaction. Examples: A piece of platinum foil is a catalyst for the combustion of methane in air.
Q:What is the maximum impact of the chemical reaction rate? Such as catalyst, temperature, concentration. If you can, you can row order.
Temperature and concentration also depends on the specific circumstances of the situation
Q:Which branch of chemistry or what specialty can study the catalyst
Inorganic Chemistry: Preparation, Synthesis, Structure and Catalytic Reaction of Inorganic Catalysts and Catalyst Carriers
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:What is the catalyst for ethylene addition water? How to play a catalytic role.
With dilute sulfuric acid can be. Sulfuric acid will be added with the addition of ethyl hydrogen sulfide, and then hydrolyzed into ethanol.
Q:What are the chemical reaction conditions in organic chemistry are catalyst and heating, please elaborate
This really does not have omnipotent law, their own more than one point, you can classify to remember, when I was in high school is in accordance with the notes, such as poly, polycondensation and the like. In general, the double triple bond addition, plus halogen is not the conditions, plus HCl, HBr and the like to heat; dehydration reaction generally concentrated H2SO4 heating, dehydration condensation is also; there are some special, such as ethylene added to ethanol Special temperature requirements, it seems that 120 degrees, there are other; other addition poly, polycondensation some need catalyst. The The In short, the conditions are many, in general, you do not go to the high school to do more questions after the feeling, encounter problems do not panic general experience can come out according to experience, this also depends on the usual accumulation, if the equation conditions Wrong to deduct points, it is not worthwhile. There are some questions when the examination will give you some information, whether you know do not know should see clearly, although some of the reaction but the subject to the conditions are not the same, when you do according to the title to write conditions, this will not wrong. In addition, thank you for your help, I do not seem to know you
Q:What is the difference between a catalyst and an oxidizing agent?
a catalyst DOES NOT take part in the reaction. it merely speeds it up. Without a catalyst, the reaction would still occur, just slower. However, reactions with oxidizing agents CANNOT and WILL NOW take place without them. They gain electrons and are also considered the thing that is reduced. At the end of the reaction, they have been altered in some way, unlike catalysts.
