Q:Which of the following statements is not true of a catalyst?
the way these choices are written they are all true but the answer could be B
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:Why are catalysts so effective in small amounts?
Catalysts don't get used up in reactions. Because of this, a single catalyst molecule can function again and again. Some catalysts are better than others for a given reaction. More effective catalysts reduce the time taken for 1/ the rate of travel of the molecule to the active site, 2/ the time the reaction takes, or 3/ the time it takes for products to diffuse away, or 4/ a combination of the above. The more effective a catalyst is in these factors, the less is needed to make it equally effective.
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 is the reaction in chemistry?
Industrial production of ammonia, ethanol, industrial synthesis of ammonia, ethanol catalytic oxidation, acetaldehyde oxidation into acetic acid, ethyl acetate preparation, the transformation of automobile exhaust, benzene substitution reaction and addition reaction, some other addition reaction of hydrocarbons, Ethanol dehydration to produce ethylene and so on
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:Catalyst & an exothermic reaction?
Catalysts work by providing an (alternative) mechanism involving a different transition state and lower activation energy. The effect of this is that more molecular collisions have the energy needed to reach the transition state. Hence, catalysts can perform reactions that, albeit thermodynamically feasible, would not run without the presence of a catalyst, or perform them much faster, more specific, or at lower temperatures. This can be observed on a Boltzmann distribution and energy profile diagram. This means that catalysts reduce the amount of energy needed to start a chemical reaction.
Q:enzymes and catalyst are....?
A catalyst is a substance that affects the rate of a reaction. It may participate, but cannot be consumed in the reaction. For example, KMnO4 catalyzes the breakdown of H2O2 into H2O and O2. In the end, as much KMnO4 exists as did in the beginning. An enzyme is a biochemical reagent that allows an organism to convert a compound into other compounds. This is part of metabolic processes. For example, maltose (a sugar composed of a chain of two glucose molecules) can be broken down into glucose by the maltase enzyme. Unlike a catalyst, enzymes may or may not be consumed/altered in the metabolic processes.
Q:Copper oxide and ferric oxide can replace manganese dioxide as a catalyst in chemical reaction?
Yes, as long as it is copper ions and iron ions on the line, such as FeCI can
Q:What is the role of the catalyst in chemical knowledge?
The catalyst is divided into: positive catalyst and negative catalyst, positive catalyst accelerates the reaction rate, and negative catalyst slows down the reaction rate. Regardless of the positive and negative of the catalyst, it only changes the rate of the reaction, does not change the nature of the reaction, and the reaction, the chemical nature of the catalyst will not change!
