Q: Does the catalyst affect the chemical reaction rate constant? How does the chemical reaction rate constant change when a positive catalyst is added to a reaction?: The catalyst will change the rate constant

Q: When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst: The habit of writing is not to write the catalyst involved in the equation, it is usually written in the equation above the equal or below

Q: In the chemical calculation, the quality of the catalyst should not be counted before and after the reaction: Half is not easy to save trouble

Q: What is the catalyst condition in the chemical equation?: Do you want to play on your computer? Trouble ah ~ no you add brackets it ~ word may be able to try ~ I have not studied ~ now look ~

Q: To write a 1500 words of small papers, so please help you busy: Change the course of the reaction

Q: Where are they good catalysts and why?? THanks!: A catalyst is a substance that speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy. Catalysts appear not to take part in the reaction. Frequently, catalysts are not very reactive. Acids and bases, on the other hand, are very reactive. Acids (as H+) and bases ( as OH-) sometimes function as catalysts in some organic reactions. They appear to be catalysts because in the course of the mechanism H+ or OH- is regenerated.

Q: What is a chemical catalyst?: A substance that participates in chemical reactions but does not change the quality and chemical properties. It can change the reactant activation energy, speed up or slow down the reaction rate.

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: Especially how can i explain the experiment with a paper and 2 paperclips with the paper acting as the catalyst.: Catalysts lower the activation energy of a given chemical reaction, thus speeding it up

Q: Chemical reactions in the presence of impurities will cause catalyst poisoning, how to understand this sentence: Catalyst poisoning reaction of raw materials contained in the trace impurities to the catalyst activity, selectivity significantly decreased or lost phenomenon. The nature of the poisoning phenomenon is a trace of impurities and the catalytic activity of the center of a chemical effect, the formation of non-active species. In the gas-solid heterogeneous catalytic reaction is formed in the adsorption complex. One is that if the toxic and active components of the role of weak, can be a simple way to restore the activity, known as reversible poisoning or temporary poisoning. The other is irreversible poisoning, it is impossible to restore the activity in a simple way. In order to reduce the side reaction activity, it is sometimes necessary to allow the catalyst to be selected for poisoning.
