- 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: Name one case in which catalyst poisoning is useful?
- Usually, catalyst poisoning is undesirable as it leads to a loss of usefulness of expensive noble metals or their complexes. However, poisoning of catalysts can be used to improve selectivities of reactions. In the classical Rosenmund reduction of acyl chlorides to aldehydes, the palladium catalyst (over barium sulfate or calcium carbonate) is poisoned by the addition of sulfur or quinoline. This system reduces triple bonds faster than double bonds allowing for an especially selective reduction. Lindlar's catalyst is another example — palladium poisoned with lead salts. As described by its inventor,[1][2] the catalyst is prepared by reduction of palladium chloride in a slurry of calcium carbonate followed by adding lead acetate. By this approach, one obtains a catalyst with a large surface area. Further deactivation of the catalyst with quinoline enhances its selectivity, preventing formation of alkanes. An example of alkyne reduction is the reduction of phenylacetylene to styrene.[1] en.wikipedia.org/wiki/Lindlar%27s...
- Q: What is the maximum impact of the chemical reaction rate? Such as catalyst, temperature, concentration. If you can, you can row order.
- The catalyst certainly affects the most
- Q: Can a catalyst react with a reactant?
- Catalysts are of different categories. There are some reactions, in which only the presence of some compound increases/decreases the rate of the reaction. In other examples, the catalyst do react with the reactants and provide a different path for the reaction. The product is formed and the catalyst is recovered. Not even a single molecule is consumed after the reaction. But if you take a sample while the reaction is going on, you might find a decrease in the concentration of the catalyst. (An example is the use of Mangnese dioxide (MnO2) in the conversion of Potassium Chlorate (KClO3) to Potassium Chloride and oxygen. The MnO2 added at the initiation of the reaction is in form of crystals and at the end of the reaction it is recovered as finely divided powder. This simply shows that MnO2 reacted with KClO3 initially and finally got detached in form of a powder.)
- Q: and what type of macromolecule are they made of? thanks!
- by definition a catalyst is a substance that alters the cost of, or makes accessible, a chemical or biochemical reaction yet maintains to be unchanged on the tip of the reaction. Enzymes are the only organic biochemical catalysts. Ribozymes are a particular sort of enzymes. certainly, the definition of enzyme rates: organic and organic catalyst produced in cells, and able to dashing up the chemical reactions mandatory for all times. they're great, complicated proteins, frequently soluble, and are noticeably specific, each and every chemical reaction requiring its very own specific enzyme. The enzyme's specificity arises from its energetic website, a community with a shape such as portion of the molecule with which it reacts (the substrate). the form of the enzyme the place the chemical binds in straightforward terms facilitates the binding of that distinctive chemical, such as a particular key in straightforward terms working a particular lock (the lock and key hypothesis). The enzyme and the substrate slot jointly forming an enzyme–substrate complicated that facilitates the reaction to ensue, and then the enzyme falls away unaltered. In prepare maximum catalysts are used to velocity up reactions. There are different non-organic and organic catalysts. maximum of that are utilized in industry and are commonly transition metals or their compounds.
- Q: Where are they good catalysts and why?? THanks!
- A catalyst is a substance that speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy. Catalysts appear not to take part in the reaction. Frequently, catalysts are not very reactive. Acids and bases, on the other hand, are very reactive. Acids (as H+) and bases ( as OH-) sometimes function as catalysts in some organic reactions. They appear to be catalysts because in the course of the mechanism H+ or OH- is regenerated.
- Q: The last question asked no one answered this question.
- First of all now the most common way to change the ligand.
- Q: What is the standard for the storage of flammable and explosive chemicals now?
- First, the basic requirements of classification of storage Dangerous goods, variety, complex performance, storage, in accordance with the zoning, classification, sub-section of the principle of special storage, set the number, set the number of fixed warehouses, fixed staff (four) custody. Small warehouses should be classified, divided, sub-stack storage, the performance of each other, fire fighting different items, dangerous dangerous goods and other general dangerous goods, should be stored separately.
- Q: Is there a catalyst for a chemical reaction?
- There may be many, but some of the catalytic effect of the catalyst is good, and perhaps some of the catalyst has not been found
- Q: What are the characteristics of the catalyst in the catalytic reaction?
- The role of the catalyst in the chemical reaction is to change the rate of chemical reaction, and its own quality and chemical properties do not change.
