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: What is the chemical vinyl chloride and benzene plus catalyst?: Looks like no ethyl benzene, it is vinyl benzene

Q: What is the catalyst for high chemistry?: Concentrated sulfuric acid, NI, barium bromide, copper or silver

Q: Will the catalyst change the reaction rate in the chemical reaction?: Many of the catalysts are specific in varying degrees, and when added to the chemical reaction system that it can catalyze, it must change the rate of chemical reaction, and of course both positively and negatively catalyzed. Chemical reaction rate, it can not be called a catalyst.

Q: What happens to a catalyst after a chemical reaction?: Only a catalyst? Poor catalyst. Catalysts get very little respect. Folks assume that catalysts don' do anything, yet they magically speed up a reaction without taking part in the reaction. That just isn't the case. Most chemical reactions take place in multiple steps. A catalyst can be a reactant in one step and a product in s subsequent step, thereby giving the impression that it did not react. The catalyst speeds up a chemical reaction by providing an alternate reaction pathway which has a lower activation energy. The lower activation energy means that more molecules will have the energy required to react, and the rate will be greater. So the bottom line is that the catalyst will have appeared not to have reacted, and returns to its original state.

Q: Chemical equation if there is a catalyst and heating, which write in the equal sign above, which written in the following? Tomorrow academic level test, solution: At the same time, the catalyst is heated

Q: What is a Catalyst?: Catalyst is a chemical substance which is used in chemical reactions in relatively small amounts to start up or increase the rate of the reaction without being consumed in the process. For example, Sulfuric Acid is used to dehydrate Ethanol to Ethylene. Enzymes in living beings are biological catalysts. Manganese dioxide, used to decompose Hydrogen Peroxide to Oxygen and Water.

Q: How does active charcoal catalyze in some chemical reactions?: Activated carbon is generally in the catalytic reaction to do more carriers, has not yet seen its catalyst to report.

Q: Does anybody have any tips or references I can go to for this? I'm writing a novel and the main character wants to be a catalyst; the story isn't about him and his journey, so much as the effects on everyone around him that come about simply because of him being there and being who he is. How would I go about doing this, and doing it well?: Ways to be a catalyst: By his behaviour: - He is a good listener. People use him as a sounding board and make important decisions as a result. - He is indiscreet and inadvertently reveals people's secrets and back-sniping comments. - He is a ****-stirring gossip. - He is a home-wrecking Lothario. - He is wise and gives good advice. - He is a hooligan who ruins businesses with vandalism, costs people their jobs and ruins relationships by beating people up. - He is a manipulative, blackmailing bastard who tries to turn every woman into a prostitute and con every man out of his money. - He is a charlatan who preaches nonsense about religion, health and business investments. By effortlessly influencing other people's behaviour: - He is famous and people try to impress him wherever he goes. - He has cancer or a disabling war wound. People admire and pity him and are shocked by his PTs mood wings. - He is gay, Muslim or a suspected paedophile and people want to persecute or cure him. - He is destitute. People argue amongst themselves over whether it's because he's lazy, has bad karma or there but for the grace of God go I. - He really looks like Jesus, Buddha or Santa and the sight of him makes people contemplate their Humanist values, coming to various conclusions. Perhaps you can write about his reputation; how he earned it, how it precedes him and provokes prejudices that he sometimes confirms or disproves. Use a detached, omniscient God-narrator. (Pretend Morgan Freeman's reading the audiobook.) Alternatively perhaps he is not a catalyst but a neurotic voyeur, fascinated by the minutiae of other people's lives so that the mundane appears tumultuous. He is not influencing people but your account of the changes in people's lives are centred on his observation of them.

Q: Can you describe at least 4 ways a catalyst can lower the activation energy of a reaction?: To see how a catalyst accelerates the reaction, we need to look at the potential energy diagram shown below which compares the non-catalytic and the catalytic reaction. For the non-catalytic reaction, the figure is simply the familiar way to visualize the Arrhenius equation: the reaction proceeds when A and B collide with succificient energy to overcome the activation barrier. The change in Gibbs free energy between reactants, A + B, and the product P is delta G. The catalytic reaction starts by bonding of the reactants A and B to the catalyst, in a spontaneous reaction. Hence, the formation of this complex is exothermic and the free energy is lowered. There then follows the reaction between A and B while they are bound to the catalyst. This step is associated with an activation energy; however, it is significantly lower than that for the uncatalyzed reaction. Finally, the product P seperates from the catalyst in an endothermic step. The energy diagram illustrates 4 ways the catalyst works : The catalyst offers an alternative path for the reaction that is energetically more favorable The activation energy of the catalytic reaction is significantly smaller than that of the uncatalyzed reaction; hence the rate of the catalytic reaction is much larger The overall change in free energy for the catalytic reaction equals that of the uncatalyzed reaction. Hence, the catalyst does not affect the equilibrium constant for the overall reaction. A catalyst cannot change the thermodynamics of a reaction but it can change the kinetics. The catalyst accelerates both the forward and the reverse reaction to the same extent. In other words, if a catalyst accelerates the formation of product P from A and B, it will do the same for the decomposition of P into A and B.
