- Q: The "one-to-two change" of the catalyst is that the quality and chemical properties of the reactants are constant or the quality and chemical properties of the catalyst are constant?
- The change in chemical reaction rate is the same as the chemical nature and quality
- Q: What are the characteristics of the catalyst in the chemical reaction?
- In simple terms: the catalyst itself is involved in the reaction, the quality of the reaction before and after the same, the ingredients do not change. The catalyst can change the rate of chemical reaction, increase the rate of reaction called catalyst, slow the inhibitor.
- Q: The quality and nature of the catalyst before and after the chemical reaction did not change this sentence wrong? Why did the "middle school student study" say it was wrong?
- The newspaper is wrong and find the teacher's theory. The
- Q: Can manganese dioxide be used as a catalyst for various chemical reactions?
- Manganese dioxide can be a catalyst for hydrogen peroxide decomposition, a catalyst for the preparation of chlorine gas from potassium chlorate, and the like can be reactants
- 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: Why extract the genome, the digestion is always not cut
- The enzyme, like the general catalyst, only catalyzes the thermodynamics of the permissible chemical reaction, shortening the time to reach the chemical equilibrium without changing the equilibrium point. The enzyme as a catalyst has no qualitative and quantitative changes before and after the chemical reaction. The mechanism of action of enzymes and general catalysts is to reduce the activation energy of the reaction.
- Q: Explain how catalysts help to reduce costs in industrial processes !?Thanks
- Catalysts are efficient at converting starting materials to the final products. Since catalysts convert these materials to the product faster, less energy will be used, and often less other materials will be used to complete the process. Both will save the company save time and money. Not to mention the catalyst can be reused, often hundreds of times before it needs to be replaced. Hope that helps!
- Q: I know that a species that does not appear in the chemical equation may also affect the rate of a reaction - e.g. a catalyst. But does that mean the catalyst can be present in the rate equation, and if so are catalysts always present in the rate equation?
- Any reaction with a finite amount of reactants has a half-life, whether it's first order, second order, zero order or complex order. The half-life (t?) is defined as the time taken for the reaction to go half-way to completion. If the reaction is: A + B ---products and A is in excess, then t? will be the time taken for half of B to be used up. For all reactions, then, you get a decay curve. For zero-order reactions, this 'curve' is a straight line, but for all other orders, the curve is an actual curve and it is quite difficult to distinguish, by visual inspection alone, whether it is exponential (indicating a first-order reaction) or hyperbolic (indicating a second or higher order reaction).
- Q: In the presence of catalyst, KCl is produced in the thermal decomposition of KClO3.You did not have a catalyst. Did you get the same products for this reaction as you would have with a catalyst?
- A catalyst changes the RATE of a reaction, not the products. So, yes, you get the same products without the catalyst as you do with the catalyst.
- Q: Is the enzyme in the enzyme bigger than gold?
- No: 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.
