- Q: What is the similarity between enzymes and general chemical catalysts?
- (1) The enzyme is the same in many respects as a biocatalyst and a general catalyst, such as a small amount and a high catalytic efficiency. As with the general catalyst, the enzyme can only change the rate of chemical reaction and does not change the equilibrium of the chemical reaction It is possible to catalyze the activation of a large number of substrates in a short time and to reflect the high efficiency of enzyme catalysis.The enzyme can reduce the activation energy of the reaction (activation) (△ G) during the reaction, but the reaction rate is accelerated and the reaction time is reduced, but the equilibrium constant is not changed. (2) However, the enzyme is a biological macromolecule (1) Enzyme-catalyzed high efficiency: The catalytic effect of the catalyst can increase the reaction rate by 10 ^ 6 ~ 10 ^ 12 times, which is at least several times higher than that of the conventional catalyst. (2) The enzyme catalyst Highly specificity: including specificity of response, substrate specificity, chirality specificity, geometric specificity, etc., that an enzyme can only act on a certain class or a specific substance. Bond, ester bond, peptide bond and so on can be catalyzed by acid-base hydrolysis, but the hydrolysis of these chemical bonds are different, respectively, the corresponding glycosidase, esterase and peptidase, that is, they were specific (3) enzymatic reaction conditions are mild: enzymatic reaction is generally carried out in aqueous solution of pH = 5 ~ 8, the reaction temperature range is 20 ~ 40 ℃
- Q: Can a catalyst decrease the rate of a chemical reaction? Please give an example if yes.
- no, by defintion the catalyst speeds up the reaction.
- Q: What about the chemical reaction of the catalyst if there is no catalyst?
- The phenomenon of accelerating or slowing the rate of chemical reactions due to the intervention of the catalyst is called catalysis. In the catalytic reaction, the catalyst reacts with the reactants to change the reaction pathway, thereby reducing the activation energy of the reaction, which is the reason why the catalyst can improve the reaction rate.
- Q: what is a catalyst ?
- A substance which initiate the rate of chemical reaction without undergoing any change by itself till the end of 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 conditional catalyst
- 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: okay im doing a project for my classroom about catalyst and i have to draw a picture but when i looked up on google i just saw a bunch of random stuff and a couple were metal so thats why im asking this question. :)
- A catalyst is something that enables a process to take place without being part of said process itself, such as in a chemical reaction.
- Q: Several experiments were carried out using catalysts
- Hydrogen peroxide in the manganese dioxide as a catalyst for decomposition reaction: 2H2O2 == MnO2 == 2H2O + O2 ↑ (laboratory oxygen principle)
- 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: role of catalyst?
- A catalyst speeds up a reaction, without itself being consumed in the reaction. Catalysts participate in reactions but are neither reactants nor products of the reaction they catalyze. They decreases the activation energy of a chemical reaction and work by providing an alternative pathway for the reaction to occur, thus reducing the activation energy and increasing the reaction rate.
