Safety:
As a matter of good industrial hygiene, gloves and safety glasses with side shields or better eye protection should be worn when handing Carbon Black ,For more information, refer to the MSDS
- Q: Why the catalyst after the chemical reaction of its quality and chemical properties unchanged
- The catalyst is only a catalytic role, not directly involved in the reaction, the current principle of its role is not clear
- 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: Cl + O3 ---> ClO + O2O + ClO ---> Cl + O2= O + O3 ----> 2O2What is the catalyst? The intermediate?How do you know which is which? If the rate law is rate=k [O3] [Cl]determine:a) the overall order.b) unit for k.c) the rate determining step, justify your answer.
- Cl is the catalyst. ClO the intermediate. The catalyst is the component which does not change in overall reaction. He forms some intermediate component(s) with the reactants. In the later reaction steps the intermediate(s) react forming the catalyst in its original state. (a) The overall order is the sum of the orders with respect to the components: n = 1 +1 = 2 (b) the unit of the rate of reaction is r [=] mol/ (Ls) (more general mol per unit time and volume) compare dimensions mol / (Ls) [=] k · mo/L · mol/L =k [=] L/(s mol) (more general unit volume per unit time and mole) (c) First reaction For elementary reaction steps the order of the reaction rate with respect to a reactant is equal to stoichiometric coefficient. Hence the rate of first reaction is: r? = k?·[Cl]·[O?] Overall rate is given by the rate determining step, while other reaction steps are in equilibrium: r = r? = k?·[Cl]·[O?] If second reaction is the rate determine step r? = k?·[O]·[ClO] while reaction 1 is at equilibrium K? = ( [ClO]·[O?] ) / ( [Cl]·[O?] ) =[ClO] = K?·( [Cl]·[O?] ) / [O?] the overall rate would be: r = r? = k?·[O]·[ClO] = K?·k?·[O]·[Cl]·[O?] / [O?] = k·[O]·[Cl]·[O?] / [O?] That doesn't match the observed rate law
- Q: What is the chemical nature of the enzyme?
- Enzyme protein and cofactor are present in the absence of catalytic activity, only these two parts together to form a complex to show the catalytic activity of this complex called the whole enzyme. Some enzymes cofactor is the metal ion, some enzyme cofactor is Organic small molecules in these organic small molecules, where the enzyme and protein binding is called the auxiliary base; and with the enzyme protein binding was more relaxed, dialysis can be used to separate the enzyme protein is called coenzyme. There is no strict boundary between the base and the coenzyme, the role of the metal ion in the enzyme molecule, or as a component of the active site of the enzyme, or the conformation necessary to form the center of the enzyme, or between the enzyme and the substrate The same coenzyme is often able to bind to a variety of different enzyme proteins, the composition of a variety of catalytic functions of different enzymes, such as coenzyme Ⅰ (NAD +) can be a variety of enzymes, As a coenzyme for many dehydrogenases, but each enzyme protein can only bind to a specific coenzyme into a whole enzyme.It can be seen that the specificity of the enzyme is the enzyme protein part of the coenzyme in the enzymatic reaction is usually responsible for electrons, atoms Or some chemical groups to determine the nature of the reaction.In recent years, it has been found that, in addition to proteins, some RNA and DNA molecules also have a catalytic effect on the chemical nature of the enzyme is the concept of protein produced a strong impact . However, the now known enzymes are essentially protein-based, or protein-dominated core components, and the concept that the enzyme is a protein-based biocatalyst does not exclude the presence of other types of catalysts, and more precisely, Can be given to the enzyme under the definition of: the enzyme is a kind of biological activity and special space conformation of biological macromolecules, including protein and nucleic acid.
- Q: Why is the catalyst in the chemical balance, the rate of change and balance?
- Plus the catalyst, but only to change the activation energy of the reaction, so that more molecules at the same time to participate in the reaction.
- Q: Comparison of biocatalysts with chemical catalysts!
- The same point: biocatalysts and chemical catalysts are selective (specific) and efficient; participate in each reaction, its own nature and quantity will not change.
- Q: Will the catalyst change in the chemical reaction?
- The catalyst is actually involved in the chemical reaction, the catalyst is added to the reaction, becomes the other material, and then the reaction becomes back, and appears to have no change, actually involved in the change, but the end result the catalyst did not change
- Q: Chemical master invited (about catalyst)
- From the thermodynamics can be reaction, and the three formulas can be added to eliminate the intermediate product, indicating that the reaction may occur. The definition of the catalyst is not complete. I am a junior undergraduate student of Jilin University School of Chemistry, according to the definition of the catalyst in the university textbook, the catalyst itself reacts with the reactants to produce unstable intermediates. After the reaction is finished, the intermediate product is explained and the catalyst is reduced. Apparently did not participate in the reaction. So the catalyst to change the course of the reaction, the original reactants to go through a relatively high energy to produce products, there will be a catalyst after a few relatively low energy barrier, so much easier, the reaction rate is greatly accelerated The It can be seen, the catalyst is not no response, but only after the completion of the reaction to restore it. It can also be seen that the amount of catalyst does not matter, and some reactions require the amount of catalyst to be approximately equal to the amount of reactants. Waiting for you to high school and university to further study on this issue will have a more clear understanding of the.
- Q: When you write a chemical equation, how do you want to add "catalyst" and "?" When you do not have to write?
- This is the need for your memory, write a few times, will naturally cooked
- Q: Does all chemical reactions have a catalyst?
- Not some reaction without catalyst
