Q:What makes an enzyme a catalyst?
D: it quickens a chemical reaction yet isn't completely replaced by skill of the reaction this is a standard definition of the understanding catalyst that a biologist gave: A chemical/substance that alters the fee of a chemical reaction yet isn't used up interior the technique.
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:What is the analytical principle of chemical adsorbents?
What do you mean by the chemical adsorber? BET is the use of the surface of the uneven force field, but the inert gas at low temperature in the surface adsorption. TPD, TPR is the number of active centers that can be measured by the technique of desorption and reduction between specific gases and catalysts as the temperature increases. If the active site is a reduced position, H2-TPR can be used. If the active site is acidic, NH3-TPD can be used, but also the method of alkali titration.
Q:What progress has chemistry brought to our life?
Q:how heterogeneous catalyst 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:What are the catalysts that appear in the chemistry experiment?
Oxygen Oxygen Oxygen Oxygen also used when the catalyst is manganese dioxide MnO2
Q:Nitrogen and hydrogen in the role of high temperature and pressure catalyst to generate ammonia chemical equation
N2 + 3H2 = catalyst, high temperature and high pressure = 2NH3
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
Q:Comparison of biocatalysts with chemical catalysts!
biocatalyst activity is adjustable, can be subject to hormones and other active regulation of hormones.
Q:What is the nature of the chemical catalyst?
The nature of the catalyst is to play a catalytic role in reducing (or increasing) the anti
