- Q: What is the principle of the catalyst? Why can change the rate of chemical reactions and their own without any change
- Because the catalyst does not participate in the reaction, it can change the rate of chemical reactions without any change in itself.
- Q: Carbon dioxide and hydrogen in the catalyst and heating conditions, the reaction of water and methane, the chemical equation is what
- CO2 + 4H2 = catalyst, heating = 2H2O + CH4
- 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: The best use of chemical catalysts
- Do not know what you want to use the best thing is what the catalyst is generally used in the process, there will be an initial induction period, the catalytic activity is relatively low, and then reached a stable catalytic state, this paragraph is generally called the catalyst life, the final Due to poisoning, active ingredient aggregation and so on factors, the catalyst activity will be reduced, then need to replace the new catalyst
- Q: what is the role of a catalyst in a chemical reaction?
- A catalyst is used to speed up a chemical reaction. It is not consumed during the reaction.
- Q: Briefly define a homogenous catalyst? Help please!?
- Define Homogenous
- Q: Could you tell me all the differences between those two catalysts? Thank you very much.
- Biochemical Catalyst
- Q: Why is the catalyst in the chemical balance, the rate of change and balance?
- But the positive reaction rate is accelerated, but also speed up the reverse reaction rate, the two increase the same multiple, so the system is still in a stable state, the same balance.
- Q: What is a Catalyst?
- catalyst is a substance that help in chemical reaction but not actually react with reactants...
- Q: how does the amount of a catalyst affect reaction rate?
- A catalyst is actually a necessary part of the reaction. The catalyst is different on in that the catalyst returns to its original state when the catalyzed reaction completes. But that means that for each atom or molecule that goes through this reaction, there must be an atom or molecule of the catalyst to combine with. You could think of the catalyst as the buses that carry the reactants to their goal. The more buses, the faster the reactants reach their goal, but at the end, all the buses are empty, just like they started.
