- Q:Chemical reaction plus catalyst on the △ H no effect
- The catalyst only affects the reaction rate of the substance and increases its activation energy, and the enthalpy change is only related to the initial state of the substance, independent of the reaction process.
- Q:Is the reaction of the exhaust purification of cars (carbon monoxide and nitrogen
- 2NO2 + 4CO = catalyst = N2 + 4CO2
- Q:The role of catalyst in chemical reactions
- Negative catalysts can be used to control the reaction rate (such as some reaction too fast, instantly release a lot of energy caused by danger, you can join), common is the antioxidant
- 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: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:A biological catalyst or a chemical reaction facilitator is know as a/an?
- I was always taught that it was something best learned by putting forth a bit of effort, reading a bit and embedding the info in your brain so you will remember it always. Just me I guess.
- Q:I have just spent CAN$550 to replace a catalyst converter at one end of the muffler. The repairman said I need to replace the oxygen sensor very soon, otherwise, the C.C. will be gone again. Is that true... can someone confirm this for me. Thanks.
- your O2 sensor measures the amount of oxygen remaining in the exhaust gas after the combustion process. The left over oxygen reacts with the sensor to send an electrical signal to your vehicles computer. the computer can then adjust your fuel injector pulse width in order to maintain the proper 14.7:1 air/fuel ratio. Excessive exhaust gases are the usual culprit when catalatyc converters fail. Even so the O2 sensor is usually fairly cheap ($20-$30) and simple to replace. I would replace it as cheap insurance
- 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 wide range of enzyme preparations are mainly cellulase, protease, amylase, pectinase, lipase, peroxidase, laccase, glucose oxidase eight categories.
- Q:In the catalyst and light conditions to break down the water to get the chemical equation of hydrogen
- 2H2O = 2H2 ↑ + O2 ↑
- Q:What is catalyst in Science?
- not all catalyst are enzymes. There are biological catalysts as well as non biological ones catalysts are something that speeds up the rate of a chemical reaction without itself getting altered after it. for example an enzyme is a catalyst because it speed up the rate of food digestion (by breaking down food molecules) and doesn't get altered after the reaction.
