- Q:In biology, the enzyme seems to be a tool for opening a reaction, such as the decomposition of cellulose, such as linked RNA and protein, no enzyme can not. But in chemistry, the catalyst is only a regulatory role, change the reaction rate only. The teacher said that the enzyme is the catalyst. Is there any other effect of the enzyme? (Ignorant high three dogs, you do not spray the big god)
- But let's not say that there is no enzyme or catalyst, the reaction can not be carried out. In the process of random collision of a molecule, the occasional jump of 3 meters is also possible, but the probability is low. From the macro point of view, is the reaction rate is low. So what rate, catalyst, or what xxx let high school teacher how to say, chemical catalysis and enzyme catalysis of the fundamental principles are the same, so you go to college to understand.
- 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.
- Q:How does active charcoal catalyze in some chemical reactions?
- Generally not, but it can be used as a catalyst carrier
- 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:Seems intuitive that it wouldn't, but I dunno the qualitative difference between activation energy & Gibbs free energy. I'M TOO LAZY TO GOOGLE I GOTS STUFF TO DO
- A catalyst can change the activation energy not the Gibbs energy. The Gibbs energy is the energy difference between the initial state and final state. A catalyst cannot change that. Imagine you are driving from school to home. How you drive do not change the height difference between the school and your home. However, a catalyst can change your path which can change the routine you drive from school to home. So if there is a hill in between your school and you home, you have the choice to drive through it or drive around. Here is a picture: upload.wikimedia.org/wikipedia/co... A catalyst can change the height of the barrier, but cannot alter the initial or final state.
- Q:Word editor when playing chemical equation = with the above conditions or how to adjust the size of the catalyst, how to make it centered,
- Open the word - insert - object - WPS3.0 formula - and then select the "label arrow template", you can add a catalyst.
- Q:The greater the chemical adsorption strength, the catalyst activity changes
- If the adsorbent is a reactant, then the better the adsorption capacity of the better catalytic effect; but the catalyst surface of the product will generally have adsorption, if this effect has become very strong, then desorption The process will become difficult, the catalytic effect will decline; the other one, if the adsorption of other substances, such as the reaction may produce a reaction or the catalyst will poison the material, it is greatly detrimental to the catalytic effect. The effect is to be controlled in a suitable optimum range for superior, and preferably to be selectively adsorbed.
- Q:Organic chemical concentration of bromine and liquid bromine What is the difference between the conditions in the iron as a catalyst can not be reacted with toluene to produce tribromotoluene? Is it possible to work with phenol to produce tribromophenol?
- The concentrated bromine water is a bromine aqueous solution and the liquid bromine is pure bromine. Only liquid bromine can produce tribromotoluene, and to add iron powder as a catalyst, and the main production is to lead bromotoluene and p-bromotoluene, tribromotoluene this content is very small.
- Q:Characteristics and types of catalysts?
- Catalysts don't undergo any change. and types of catalysts - 1) Homogeneous Catalysts ( Having same phase that of reactant, product i.e. reactant and product and catalysts all are either liquid or gas or solid.). 2) Hetrogenrous Catalysts (Different Phase than that of reactant and product. 3) Autocatalysts (reaction proceed catalysed as product is formed or product catalyse the reaction.)
- Q:What about the chemical reaction of the catalyst if there is no catalyst?
- The reaction rate will change
