- Q:High chemistry: Does the catalyst affect the heat and heat of the reaction?
- No
- Q:how does the amount of a catalyst affect reaction rate?
- It's more the surface area than the amount, but, in general, the more catalyst exposed, the quicker the reaction will proceed.
- Q:What is the difference between a catalyst and an oxidizing agent?
- a catalyst DOES NOT take part in the reaction. it merely speeds it up. Without a catalyst, the reaction would still occur, just slower. However, reactions with oxidizing agents CANNOT and WILL NOW take place without them. They gain electrons and are also considered the thing that is reduced. At the end of the reaction, they have been altered in some way, unlike catalysts.
- Q:What is the meaning of catalyst in chemistry?
- In the chemical reaction can change the reaction rate of chemical reaction (increase or decrease) without changing the chemical balance, and its own quality and chemical properties in the chemical reaction before and after the material did not change the catalyst.
- Q:How to poison the catalyst. What can be done?
- In the reactants or catalyst mixed with a small amount of material, so that the catalyst catalytic capacity of a sharp decline or even loss, this phenomenon is called catalyst poisoning. For example, in the synthesis of ammonia feed gas containing CO, CO2 and H2S, PH3, water vapor and other impurities, can make iron catalyst poisoning; contact with the system of sulfuric acid, if arsenic and selenium oxide (As2O3, SeO2), can make vanadium catalyst Loss of activity. Therefore, it is necessary to purify the feed gas, prevent the poisoning of the catalyst, and also reduce the corrosion of the equipment. The phenomenon of catalyst poisoning is sometimes temporary, the removal of toxicants, the effectiveness of the catalyst can still be restored; sometimes it is permanent, without chemical treatment can not restore catalytic performance.
- Q:Is the chemical reaction rate constant related to the amount of catalyst used?
- The decomposition of hydrogen peroxide, manganese dioxide in addition to the catalyst, but also in which it can be considered a carrier (from the surface of manganese dioxide to emit small bubbles, you should be able to see), so the amount of more than certainly can speed up the reaction.
- Q:What are the requirements for the catalyst for the chemical industry?
- Generally find a few, according to the cost and cost of cost, choose cost-effective
- Q:What is a catalyst and how does it make a reaction go faster?
- a catalyst is a substance used to increase and decrease the rate of a chemical reaction....it makes the reaction go faster due to chemical changes it may hav certain characteristics which help in makingthe reaction fast
- Q:I think doubling the concentration of catalyst will double the rate of a reaction (K2/K1 =2). I want to confirm. This is for my project work. Please reply as soon as possible.
- A catalyst speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy, thus increasing the number of collisions that can result in the formation of product. When the catalyst is a reactant in the rate determining step, and the reaction is first order in the catalyst, then a doubling of the concentration will double the rate. But if the rate determining step which includes the catalyst is not first order, then doubling the concentration won't double the rate. Then there is the case of a heterogeneous catalyst in which the reaction is essentially zero order in the catalyst. The amount of catalyst won't affect the speed of the reaction beyond the initial increase. The mere fact that the catalyst is present speeds up the reaction.
