- Q: Like biological and industrial reations. Thanks.
- Reactions that have high Activation Energy need catalysts to speed up reactions. These reactions aren't spontaneous since the reactants do not have enough energy to overcome the activation energy barrier. Catalysts are compounds that speed up reactions by providing an alternative pathway for the reaction. It is a common misconception that catalysts lower the activation energy. It doesn't actually lower the activation energy, instead it provides an alternative pathway with lower activation energy. For example, breakdown of hydrogen peroxide happens in nature but, relatively slowly. When you add a little bit of manganese dioxide, the breakdown happens a lot faster. Another example is, breakdown of glucose in the body. It is facilitated by an enzyme called amylase (or carbohydrase). An industrial example is the use of vanadium pentoxide (V2O5) in the Contact process, where SO2 is converted to SO3 in the presence of V2O5. Hope that helps!
- Q: How are the 4 characteristics of a catalyst (1. organic or inorganic 2. reusable 3. Highly specific, and 4. lowers activation energy) important in preforming life functions? please be as specific as possible, i understand that these are characteristic, i just don't understand why they're beneficial, other than the reusable and lowers activation energy one.
- Organic or Inorganic - the catalyst (enzyme) must be organic to be found in the cell. Catalysts speed up chemical reactions inside a cell and must therefore be organic to be a functioning part of the cell. Reusable - There are so many reactions that catalysts are involved in that it would be a waste for the cell if a catalyst could only last one reaction, especially if there are inhibitors and competition for the active site. Catalysts must be reusable in order to keep the cell functioning. Catalysts always remain unchanged after a reaction. HIihly Specific - Catalysts are only made to catalyze one specific chemical reaction. Their active site has proteins bonded in such a way that only certain elements can enter the active site and H bond with those proteins. The fact that they are highly specific maximizes the productiveness of the cell. And it ensures that the cell only has catalysts to reactions that it needs to be completed. It also ensures that the elements are correctly bonded with eachother. If any two elements could enter the active site, there is no guarantee that the correct product will be produced. Catalysts and Enzymes must be super highly specific in order to properly function. Lowers Activation Energy - The more energy a cell has to spend to catalye a reaction, the worse it is for the cell and the less ATP is has for other reactions. Catalyts hold the substrates together so there is less energy that is needed to have the two substrates react with eachother. Activation Energy is the energy that is needed to start a reaction. So the less energy used by the cell for reactions, the better for the cell. Hope this helps
- Q: How does the chemical equation calculate the quality of the catalyst?
- So the reactant mass is equal to the quality of the product, with the quality of conservation
- Q: What is the PTC catalyst in chemistry?
- 1, polyether chain polyethylene glycol: H (OCH2CH2) nOH chain polyethylene glycol dialkyl ether: R (OCH2CH2) nOR2, cyclic crown ethers: 18 crown 6,15 crown 5, Fine and so on. 3, quaternary ammonium salt: commonly used quaternary ammonium salt phase transfer catalyst is benzyl triethyl ammonium chloride (TEBA), tetrabutyl ammonium bromide, tetrabutylammonium chloride, tetrabutylammonium hydrogen sulfate (TBAB) , Trioctylmethylammonium chloride, dodecyltrimethylammonium chloride, tetradecyltrimethylammonium chloride, and the like. 4, tertiary amine: R4N X, pyridine, tributylamine and the like. 5, quaternary ammonium base (its alkaline and sodium hydroxide similar) soluble in water, strong hygroscopicity. 6, quaternary phosphonium
- Q: What is the difference between biological and chemical catalysts?
- Biological catalyst: 1. Biological catalysts or enzymes are high molecular weight globular proteins. 2.Their composition may change at the end of reaction. 3.Their catalyzing effect is very high. i.e faster than chemical catalyst. 4.They are reaction specific. i.e One enzyme or biological catalyst may catalyze only particular type of reaction and not many. 5.They are intolerant to temperature and pH changes. An enzyme can not function outside its temperature or pH range. e.g amylase,lipase,pepsin Chemical catalyst: 1.Chemical catalysts are simple inorganic molecules with low molecular weight. 2.They remain unchanged at the end of reaction. 3.They are slower compared to enzymes. 4.They are not reaction specific. 5.They function within wide range of temperatures,pH or pressure. e.g vanadium dioxide, platinum
- Q: Why extract the genome, the digestion is always not cut
- The specificity of enzymes is very strict, those compounds that are considered symmetric in organic chemistry such as glycerol, ethanol, citric acid, etc., are asymmetric (even with the same groups) when they are used as substrates for enzymes, That is, their location in space, after all, different (available "three-point landing" theory explained, 1948 Oqston proposed).
- Q: Please name 2 common examples of catalysts.Thank you?
- Well, there's Adam's Catalyst (PtO2) which is one of the most used catalysts.
- 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: Before and after the chemical reaction, the nature of the catalyst unchanged this statement right? Why?
- Chemical properties do not change better. Some properties of the catalyst may change before and after the reaction. If the experiment proves, the state of the catalyst before and after the reaction changes, and some changes from powder to powder.
- Q: Chemical reactions in the presence of impurities will cause catalyst poisoning, how to understand this sentence
- This is in the chemical balance, but also alone
