- Q: High school knowledge __ teacher do not know right!
- Nothing to do, but with the percentage of activated molecules, is proportional to
- Q: Are biological enzymes harmful to humans?
- A biological enzyme is a biocatalyst that is produced or extracted from a biological organism. The catalyst is a substance that accelerates the chemical reaction and does not change itself in the chemical reaction. In layman's terms, the catalyst is a special substance that catalyzes it. Enzyme as a member of the catalyst family has its own special properties. Each of the biological enzymes will only selectively react to some chemical reactions. A biological enzyme is equivalent to a key that opens a complex compound whose importance is that its unique structure or multidimensional shape matches a part of the group. Once these two parts are combined, the specific chemical bond in the group molecule changes as if the lock was opened. When the reaction is completed, the enzyme is released and repeated with the next group, followed by repeated repeats. Many chemical reactions in the normal temperature conditions, the reaction is very slow so that the whole process is difficult to be perceived.
- Q: Why the catalyst is required to have a large surface area and a rich pore structure
- Has a large surface area, is the reactants and catalyst contact more fully, improve the catalytic effect
- Q: What are the properties of the catalyst (eg, specificity)?
- The definition of a chemical reaction in the chemical reaction can change the chemical reaction rate of other substances, and its quality and chemical properties before and after the reaction did not change the material called catalyst, also known as catalyst. Catalyst in the role of chemical reaction There is also a saying that the catalyst reacts first with one of the reactants and then the two products continue to undergo a new chemical reaction under the original conditions and the reaction conditions of the catalyst reaction are more reactive than the original reaction The reaction conditions of the catalyst have been changed by the reaction of the catalyst by the reaction of the catalyst, that is, the quality and chemical properties mentioned above did not change before and after the reaction.
- Q: Can manganese dioxide be used as a catalyst for various chemical reactions?
- he catalyst does not participate in the reaction, such as on the platinum - rhodium alloy network, nitrogen and hydrogen reaction to produce ammonia .Piplatin - rhodium alloy network in the process of providing electrons (or similar effects, the specific is not clear, but does not react itself), the reaction Before and after the platinum - rhodium alloy network shape has not changed.
- Q: Describe the role of a catalyst and a substrate in a chemical reaction.
- a catalyst lowers the activation energy of a reaction. By lowering the activation energy, the internal kinetic energy the reactants become sufficient for the reaction to occur on a much larger scale and thus appear faster. Without the catalyst, you would depend on the statistical probabilities of small numbers of reactant particles having enough internal kinetic energy to overcome the activation barrier. a substrate is merely the substance in the reaction being catalyzed
- Q: Does increasing the amount of catalyst added to, say, a solution of Hydrogen Peroxide, make the rate of reaction go faster. Is the rate of reaction directly proportional to the amount of catalyst added to the solution? Or does the experiment go at the same rate regardless of how much catalyst there is? Thanks would really appreciate some answers. - Sarah
- Catalyst do not participate in the reaction but it speeds up the reaction. If you increase the amount of catalyst from the required amount, it would somehow negates its positive response or it would result in producing another product.
- Q: Can the catalyst be a reactant in chemistry?
- In the chemical reaction can change the chemical reaction rate of other substances (both improve and reduce), and its own quality and chemical properties in the chemical reaction before and after the material did not change called catalyst. [From the definition of reactants. To
- Q: Just something I've always wondered about...
- transition okorder /... for ex-- X (one reactant) + catalyst(transition element) ------X.catalyst(intermediate unstable compound) X.catalyst + Y (other reactant) --------XY(product) + catalyst how the change in oxidation state of transition elements helps the reacton through the formation of intermediates may be seen from reaction in between SO2 and O2 to form SO3 in presence of V2O5 ... V2O5 + SO2 ------V2O4 + SO3 2V2O4 + O2 ------2V2O5 in the above reaction vanadium changes its oxidation state from +5 to +4 and again to +5.. another example is reaction in between iodide and persulphate ions in presence of Fe(III) as catalyst... 2I(-) + S2O8(2-) ---------I2 + 2SO4(2-) (Fe(III) is present as catalyst) the reaction is believed to take place as follows: 2Fe(3+) + 2I(-) ------2Fe(2+) + I2 2Fe(2+) + S2O8(2-) ------2Fe(3+) + 2SO4(2-) (3)in number of cases transition elements provide a suitable large surface area with free valencies on which reactants are absorbed ...as a result concentration of reactants on surface of catalysts increases..hence rate of reaction increases...this is known as adsorption theory.... according to adsorption theory : there are free valencies on surface of solid transition metals because of the incomplete d-subshelll.. so the mechanism of catalysis involve followin five steps: (1) diffusion of reactant molecules towards surface of catalyst... (2) adsorption of reactant molecules on surface of catalyst by forming loose bonds with catalyst due to free valencies... (3)occurence of chemical reactions between reactant and catalyst forming an intermediate.. (4)desorption of product molecules from surface due to its lack of affinity for the catalyst surface thereby making the surface free for fresh adsorption of reactant molecules... (5)diffusion of product molecules away from surface of catalyst...
- Q: Is it not the rate to accelerate the addition of the catalyst to the catalyst, and that is why the balance does not move
- If the reaction before the catalyst, you can speed up the reaction rate, that is to achieve the balance required to reduce the time, but to balance the system when the same concentration
