- Q: Pls help me define a catalyst.?
- catalyst is a substance which increases or decreases the rate of recation without being involve in the reaction
- Q: Who knows hydrogen and nitrogen in the high temperature, high pressure and catalyst conditions for the synthesis of ammonia chemical equation ah? Urgent! The SOS
- 3H2 + N2 ===== 2NH3
- Q: Does anybody have any tips or references I can go to for this? I'm writing a novel and the main character wants to be a catalyst; the story isn't about him and his journey, so much as the effects on everyone around him that come about simply because of him being there and being who he is. How would I go about doing this, and doing it well?
- Ways to be a catalyst: By his behaviour: - He is a good listener. People use him as a sounding board and make important decisions as a result. - He is indiscreet and inadvertently reveals people's secrets and back-sniping comments. - He is a ****-stirring gossip. - He is a home-wrecking Lothario. - He is wise and gives good advice. - He is a hooligan who ruins businesses with vandalism, costs people their jobs and ruins relationships by beating people up. - He is a manipulative, blackmailing bastard who tries to turn every woman into a prostitute and con every man out of his money. - He is a charlatan who preaches nonsense about religion, health and business investments. By effortlessly influencing other people's behaviour: - He is famous and people try to impress him wherever he goes. - He has cancer or a disabling war wound. People admire and pity him and are shocked by his PTs mood wings. - He is gay, Muslim or a suspected paedophile and people want to persecute or cure him. - He is destitute. People argue amongst themselves over whether it's because he's lazy, has bad karma or there but for the grace of God go I. - He really looks like Jesus, Buddha or Santa and the sight of him makes people contemplate their Humanist values, coming to various conclusions. Perhaps you can write about his reputation; how he earned it, how it precedes him and provokes prejudices that he sometimes confirms or disproves. Use a detached, omniscient God-narrator. (Pretend Morgan Freeman's reading the audiobook.) Alternatively perhaps he is not a catalyst but a neurotic voyeur, fascinated by the minutiae of other people's lives so that the mundane appears tumultuous. He is not influencing people but your account of the changes in people's lives are centred on his observation of them.
- Q: What is the reaction in chemistry?
- Industrial production of ammonia, ethanol, industrial synthesis of ammonia, ethanol catalytic oxidation, acetaldehyde oxidation into acetic acid, ethyl acetate preparation, the transformation of automobile exhaust, benzene substitution reaction and addition reaction, some other addition reaction of hydrocarbons, Ethanol dehydration to produce ethylene and so on
- Q: It's a GCSE Chemistry questionI just need to know why there are so many
- Many important chemical reactions require inputs of energy to proceed. If a catalyst is present less energy will be required to complete the reaction. Catalysts are substances that are mixed in with materials that are to be reacted, but they themselves do not, in the end, change chemically. They establish a local environment that promotes one or more chemical reactions to take place. A catalyst is important in many industrial processes. Sulfuric acid, which is used to produce batteries, detergents, dyes, explosives, plastics, and many other produces, is commonly produced using a catalyst called vanadium oxide. Ammonia, a primary component of many fertilizers, could not be produced economically without the use of iron oxide which speed up the reaction. The process of catalyst also affects the state of our global environment. Automobiles use catalytic converters to treat exhaust. The metals platinum and palladium facilitate the chemical conversion of noxious gases to more inert forms, greatly decreasing the environmental impact of combustion engines. Probably the most important impact of catalyst is on life itself. All important biochemical reactions are catalyzed by molecules called enzymes. Most enzymes are proteins which catalyze specific reactions within cells. Some examples include polymerases, which synthesize DNS and RNA, peptidases, which digest protein, and ATP synthases, which produce energy for the many different cell activities.
- 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: Just something I've always wondered about...
- there are so much catalysts made up of transition metals. because one of the characteristics of transition metals is can be made to catalyst. one of the catalyst that is mostly used is iron fillings which is used as catalyst to make ammonia from nitrogen gas and hydrogen gas.
- Q: What is the meaning of catalyst in chemistry?
- In the chemical reaction can change the reaction rate of chemical reaction (increase or decrease) without changing the chemical balance, and its own quality and chemical properties in the chemical reaction before and after the material did not change the catalyst.
