Our Factory:
- Q: What is the superiority of the catalyst compared to the stoichiometric reagent?
- Efficient: The catalytic efficiency of the enzyme is higher than that of the inorganic catalyst, making the reaction rate faster;
- Q: Exemplify the use of green catalysts in green chemistry
- The platinum and palladium catalyst in the exhaust pipe of the automobile can catalyze the formation of CO2 and N2 by NO and CO
- Q: What is the chemical nature of the enzyme?
- Enzyme is an amphoteric electrolyte, soluble in water, easy to precipitate at the isoelectric point, the enzyme activity-pH curve and the zwitterion of the enzyme. The enzyme is a high-molecular colloidal material, generally can not pass through the semipermeable membrane; Dissociation curve similar to the enzyme in the electric field can be the same as other proteins swimming; ③ lead to protein denaturation factors, such as ultraviolet, heat, surfactant, heavy metals, protein precipitants, etc., can make the enzyme failure; Protease hydrolysis and loss of activity.In addition, the most direct evidence is that all has been highly purified and crystallized enzyme for a primary structure analysis, the results indicate that the enzyme is a protein.
- Q: Chemistry why the catalyst can be equal to speed up the positive reaction rate
- Since the catalyst only changes the activation energy and the amount of reactivity can be reduced, the amount of reaction energy is also reduced. Therefore, a positive catalyst is also a good catalyst for its reaction. Speed up the same multiple.
- Q: What is a Catalyst?
- catalyst is a substance that help in chemical reaction but not actually react with reactants...
- Q: What is the difference between biological enzymes and chemical catalysts?
- Biological enzyme is a protein, according to the mild reaction conditions, high specificity, the advantages of strong catalytic capacity,
- Q: What is the catalytic efficiency of ordinary chemical catalysts?
- Different reactions, with the same catalyst, the catalytic efficiency is different. The same reaction, with different catalysts, the catalytic efficiency is also different
- Q: Is it possible for the different chemical reactions to have the same catalyst?
- Right, think about the catalysis of biological enzymes
- 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: How does the catalyst generally add to the organic chemical reaction?
- In the case of heterogeneous catalysis, the specific surface of the catalyst, in addition to the activity of the catalyst, is an important factor in determining the reaction rate, which means that the specific surface for catalysis is large and the reaction is as fast as the whole. So the overall principle in understanding the activity of the premise of the catalyst, would like to quickly add a little more.
