- Q:How does the chemical equation calculate the quality of the catalyst?
- Catalyst, the quality of the reaction before and after the same, the same chemical properties.
- Q:What is a catalyst in a chemical reaction?
- A catalyst increases the rate of a reaction by lowering the activation energy. Activation energy is the energy required to make the reactants form the products. If the activation energy is lower the reaction takes place faster and more easily. Also catalysts are not used up during the reaction.
- Q:What is the catalyst for industrial aluminum electrolysis?
- 2AlCl3 (melt) = power = 3cl2 + 2al by-product is chlorine
- Q:In chemistry what is a catalyst and an example?
- A catalyst is a liquid or a gas you can add to a substance to make it react quicker and/or upon itself or another chemical. A catalyst can be one chemical you add to another that causes a significant reaction or they could be variables in an experiment (like temperature) can be a catalyst. It could also be a liquid/gas that you add to a substance to neutralize it or make it safe to clean/touch/handle. For instance if you spill chemicals in a biology lab, you have to add a catalyst (generally water or clarifying soap) to make it safe to clean up. Hope I could help.
- Q:what is the role of a catalyst in a chemical reaction?
- A catalyst speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy. Since the activation energy is lower, more product will be formed in the same amount of time. Chemists used to assume that a catalyst somehow sped up a reaction without being consumed in the reaction. We now know that a catalyst will be a reactant in one step of a reaction mechanism, and will be a product in a subsequent step in the mechanism, so that it **appears** that the catalyst does not take part in the reaction. ======== Follow up ========= Remember, it is customary to cite one's sources when quoting from another source or when simply copying large passages from Wikipedia or some other web page.
- Q:CO and NO react under the action of a catalyst to generate chemical formulas for CO2 and N2.
- N from +2 to 0 price 2e * 2
- Q:Chemical Reactions Under what circumstances the catalyst accelerates the reaction
- First, more than ninety-nine percent of the catalyst is accelerating the reaction, and if the catalyst kinetics reduces the energy barrier of the reaction, the reaction will naturally accelerate.
- Q:What is the analytical principle of chemical adsorbents? How about the number of active catalyst centers tested?
- 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:To write a 1500 words of small papers, so please help you busy
- Change the course of the reaction
- Q:My chemistry teacher wont tell me because it's in the higher course. And i'm not waiting a whole year to find out. And also, google is being a gimp about it. So thanks a lot if you know, I only have basic chemistry knowledge btw, lumen'ss terms if you can.
- Catalysts facilitate the reaction. They might work in several ways. Here is an example: Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process regenerating the catalyst. The following is a typical reaction scheme, where C represents the catalyst, X and Y are reactants, and Z is the product of the reaction of X and Y: X + C → XC (1) Y + XC → XYC (2) XYC → CZ (3) CZ → C + Z (4) Although the catalyst is consumed by reaction 1, it is subsequently produced by reaction 4, so for the overall reaction: X + Y → Z They might also just increase the surface area, thus speeding up the reaction. Example: Coke looses its fizz over time if left with the cork unscrewed. This is because the HCO3 is released as CO2. If you drop a menthos into the coke, it explodes with CO2, because the methos is full of tiny dents in the surface (thus giving it a massive surface area). (i blatantly copied the first example from the wiki)
