- Q:Explain how catalysts help to reduce costs in industrial processes !?Thanks
- They speed up a reaction, allowing you to get more product more quickly and remain unchanged, therefore you can use them over and over again.
- 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:What is the catalyst condition in the chemical equation?
- I studied three methods ~ word which can be used to give me a mailbox to the word text to pass you ~
- Q:Does a catalyst work for both reactants and products?From my understanding, organic catalyst or enzyme does not necessarily work for the product of the reaction because of the shape of the activation site. However I cannot speak for inorganic ones.
- A catalyst works for either the reactants or the product in a given reaction. If it works for the reactants then the activation site on the enzyme, for example, will only fit on the reactants. If a catalyst is added to a reaction in which it catalyzes the back-reaction, or it aids the products, then the reaction will be reversed. i don't think a catalyst could work for both the reactants and products in one reaction because it wouldn't really be a catalyst anymore; it wouldn't make the rxn progress any faster since it would be canceling out itself by aiding both the reactants and the products. I think this is what you are asking, if not please post more details. I hope I didn't confuse you even more!
- Q:Exemplify the use of green catalysts in green chemistry
- The platinum and palladium catalyst in the exhaust pipe of the automobile can catalyze the formation of CO2 and N2 by NO and CO
- Q:What kind of chemical substances can seriously damage the ozone layer, as a catalyst or reactants can be?
- Hundreds of years ago the news once the industrial production and emissions of ozone generated less way, the ozone layer will still be thin.
- Q:The beginning of the chemistry plus the catalyst and the plot without the Cuihua agent
- Plus the rate of fast
- Q:What kind of chemical reaction requires a catalyst?
- Too much reaction, and basically related to the industry
- Q:Will the catalyst change in the chemical reaction?
- In fact, there are two kinds of catalyst mechanism, one is not a chemical reaction, the reaction did not occur throughout the chemical reaction, the catalyst did not change; one is involved in the reaction process, but the final production of the catalyst, which The class reaction generally occurs in a stepwise chemical reaction.
- Q:A substance involved in chemical reflection, but reflects the quality of the material before and after the change, you say it is a catalyst?
- Is a catalyst. Principle and burning black copper wire and ethanol reaction to produce acetaldehyde the same
