- 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.
- Q:What is the catalyst condition in the chemical equation?
- Do you want to play on your computer? Trouble ah ~ no you add brackets it ~ word may be able to try ~ I have not studied ~ now look ~
- Q:A catalyst elevates the rate of a reaction by?
- reducing the energy required for the reactants to reach the transition state.
- Q:the process of which the heterogeneous catalyst work in vehicles. a step by step instruction in how they work. :)
- The Reduction Catalyst The reduction catalyst is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the NOx emissions. When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. For example: 2NO =N2 + O2 or 2NO2 =N2 + 2O2 The Oxidization Catalyst The oxidation catalyst is the second stage of the catalytic converter. It reduces the unburned hydrocarbons and carbon monoxide by burning (oxidizing) them over a platinum and palladium catalyst. This catalyst aids the reaction of the CO and hydrocarbons with the remaining oxygen in the exhaust gas. For example: 2CO + O2 =2CO2
- Q:The beginning of the chemistry plus the catalyst and the plot without the Cuihua agent
- What image, rate or balance?
- Q:In chemistry what is a catalyst and an example?
- Catalysts are substances that increase the rate of a reaction by providing a low energy shortcut from reactants to products. In some cases, reactions occur so slowly that without a catalyst, they are of little value. Nearly all reactions that occur in living cells require catalysts called enzymes- without them, life would be impossible. There are two important classes of catalysts: homogenous catalysts like enzymes and aqueous ions that are uniformly mixed with the reactants, and heterogeneous catalysts that provide a surface that holds and reconfigures the reactants in a way that is favorable for reaction. Examples of homogeneous catalysis. Catalysts in solution with the reactants usually provide fast reaction paths by allowing reactants to form an unstable intermediate that quickly decomposes into products. For example, the substitution reaction CH3CH2OH(g) + HCl(g) H2SO4 ----->CH3CH2Cl + H2O(ell) is catalyzed by acid because the ethanol is converted into unstable CH3CH2OH2+, which quickly reacts with Cl- to produce the products. Definition: A catalyst is a subtance that increases the rate of a chemical reaction by reducing the activation energy, but which is left unchanged by the reaction. Examples: A piece of platinum foil is a catalyst for the combustion of methane in air.
- Q:Can some chemical reactions have a variety of catalysts that are correct or wrong?
- Very correct, many reactions can have a lot of catalyst. Such as hydrogen peroxide decomposition can be used manganese dioxide or fe destroy
- Q:Junior high school chemistry - chemical reaction before and after the quality and chemical properties of the material must be the catalyst?
- It is not always possible that the equivalent reaction, i.e. one or more of the reactants, is the same as the relative atomic mass of one or more of the products and the coefficients in the chemical equation are the same
- Q:Can a catalyst react with a reactant?
- Catalysts are of different categories. There are some reactions, in which only the presence of some compound increases/decreases the rate of the reaction. In other examples, the catalyst do react with the reactants and provide a different path for the reaction. The product is formed and the catalyst is recovered. Not even a single molecule is consumed after the reaction. But if you take a sample while the reaction is going on, you might find a decrease in the concentration of the catalyst. (An example is the use of Mangnese dioxide (MnO2) in the conversion of Potassium Chlorate (KClO3) to Potassium Chloride and oxygen. The MnO2 added at the initiation of the reaction is in form of crystals and at the end of the reaction it is recovered as finely divided powder. This simply shows that MnO2 reacted with KClO3 initially and finally got detached in form of a powder.)
- Q:Brief introduction of enzyme as biocatalyst and general chemical catalyst and its personality
- can only change the rate of chemical reaction, do not change the equilibrium point of the chemical reaction, the enzyme itself does not change before and after the chemical reaction (3) can reduce the chemical reaction of the activation energy The
