Q:what is the role of a catalyst in a chemical reaction?: A catalyst speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy. Since the activation energy is lower, more product will be formed in the same amount of time. Chemists used to assume that a catalyst somehow sped up a reaction without being consumed in the reaction. We now know that a catalyst will be a reactant in one step of a reaction mechanism, and will be a product in a subsequent step in the mechanism, so that it **appears** that the catalyst does not take part in the reaction. ======== Follow up ========= Remember, it is customary to cite one's sources when quoting from another source or when simply copying large passages from Wikipedia or some other web page.

Q:What about the chemical reaction of the catalyst if there is no catalyst?: The catalyst used to heat and hold, the material will not react between.

Q:in my 99 ram 2500 v8 5.9 that code came up, not sure what to do about it or what it could be any ideas or help with be great thanks: In after Robert M phaggotry. Oh, like that first poster said, be sure there aren't other faults causing the rear O2 sensor to pick up all that O2 in the exhaust...such as a rich-running engine.

Q:I know that a species that does not appear in the chemical equation may also affect the rate of a reaction - e.g. a catalyst. But does that mean the catalyst can be present in the rate equation, and if so are catalysts always present in the rate equation?: Yes, a catalyst can be included in a rate law. That's because, most reactions occur in a series of step and the rate is based on the rate determining step, which is the slowest step. A catalyst may be a reactant in the rate determining step, and a product in a subsequent step. Therefore, the catalyst is not included in the overall reaction. But a catalyst need not always be in the rate law. The rate law is usually based on the rate determining step. ========== Follow up =========== In the free response questions on the AP chemistry exam there has been at least one case where a rate law included a catalyst( 2002D). Brown and LeMay always include at least one in their examples, and I always cover this situation when I teach rate laws and mechanisms in AP chemistry. Here is one comment: Other examples of species not in the balanced reaction occurring in the rate law would include catalysis, where a catalyst does not normally appear in the balanced reaction but does appear in the rate law. www.chem.arizona.edu/~salzmanr/48... Consider this generalized reaction which is catalyzed by M A + B --C A + M --Q ... slow Q + B --C ... fast M is the catalyst, and Q is the intermediate. The slow, or rate determining step, depends only on the concentrations of A and M, the catalyst. So even though the overall reaction does not include, M, the rate law does. Rate = k[A][M]

Q:Are biological enzymes harmful to humans?: Biological enzymes through scientists more than a century of research, usually known as more than 3,000 kinds of enzymes, the current application of biological enzymes in the textile a wide range of technology, fiber modification, silk degumming, raw hemp (ramie, linen, Kenaf) degumming, dyeing and finishing of the desizing, refining, finishing and net cleaning processing, textile printing and dyeing wastewater treatment and garment processing and other aspects of the application. Enzyme technology has a unique advantage in improving dyeing and finishing processes, saving energy, reducing environmental pollution, improving product quality, adding value and developing new raw materials. At present in the textile processing using a wider range of enzyme system

Q:The role and significance of chemical catalysts: The catalyst does not participate in the reaction, but only acts as a catalyst, and finally gets the catalyst composition unchanged. But if the catalyst, your reaction will be very slow or even not happen.

Q:What is a Catalyst?: Catalyst is a chemical substance which is used in chemical reactions in relatively small amounts to start up or increase the rate of the reaction without being consumed in the process. For example, Sulfuric Acid is used to dehydrate Ethanol to Ethylene. Enzymes in living beings are biological catalysts. Manganese dioxide, used to decompose Hydrogen Peroxide to Oxygen and Water. For detailed answer.... en.wikipedia.org/wiki/Catalysis

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:Have you Read it ? If SoCan You Think Of Any Good Group Discussion Questions ?: Discussion and Essay Questions What is a catalyst? Who are the catalysts in this book? Why? What is Kate running from? How did she get lost (literally and figuratively)? Why does Kate hate English class? What are some of the myths surrounding the college application process? About high school? About kids like Kate? Kids like Teri? Find the list of vocabulary words given out for homework in Kate's English class. The author deliberately chose them. What is their significance? Why do authors do things like that? Does this make you hate authors? (joke... just wanted to see if you're paying attention) Discuss these image systems (symbols) found in the book: a. chemistry b. periodic table c. vision/sight d. movement vs. being stuck e. electricity What examples of safety awareness and danger can you find? How are they connected to each other? Make a list of all the elements and chemical terms used as chapter headings in the book. Explain how the chapters headings refer to the action with each chapter. Find the hints of Alice in Wonderland in the book. How does the story of Alice's journey reflect Kate's? Catalyst takes place in Merryweather High School, also the setting for Speak. What connections link the two books? How is food used in this book? Why don't we learn more about the life of Teri Litch (hint: examine the book's POV) How is Kate's relationship with her father? Why is it that way? Does it change over the course of the book. (Give examples for each answer.) Discuss the role of religion in this book. What does Kate believe in? Teri? Mitchell? How and why does Kate's relationship with Teri change after Mikey's death? Why are the three sections of the book labeled Solid, Liquid and Gas? Who is the most important character in this book? Why? How do the characters in Catalyst deal with defeat?

Q:chemistry subject: Catalyst is the substance used to enhance or reduce the speed of a reaction.. there are thousand of catalyst used..(product of one reaction may act as catalyst of another).. you can see in google
