- Q: Chemical questions: "CO2 and H2 in the catalyst conditions have a reaction, the reaction of the chemical equation is"
- CO2 + H2 = CO + H2O (conditions: catalyst, generally already heating, and reversible)
- Q: What is a catalyst in a chemical reaction?
- A catalyst provides an alternative reaction pathway with a lower activation energy. So it speeds up the rate of reaciton because the energy of the particles/reactants doesnt have to be that high to OVERCOME the activation energy so it can therefore react. The activation energy is the minimum amount of energy required for particles to react, so the lower it is, the more faster a rate of reaction will be.
- Q: What happens to a catalyst after a chemical reaction?
- Only a catalyst? Poor catalyst. Catalysts get very little respect. Folks assume that catalysts don' do anything, yet they magically speed up a reaction without taking part in the reaction. That just isn't the case. Most chemical reactions take place in multiple steps. A catalyst can be a reactant in one step and a product in s subsequent step, thereby giving the impression that it did not react. The catalyst speeds up a chemical reaction by providing an alternate reaction pathway which has a lower activation energy. The lower activation energy means that more molecules will have the energy required to react, and the rate will be greater. So the bottom line is that the catalyst will have appeared not to have reacted, and returns to its original state.
- Q: Chemical catalyst in several ways
- From the mechanism of the words of some of the adsorption is such as catalytic hydrogen in the Pt gas
- Q: What suitable catalysts can I use for the reaction between Hydrochloric acid and zinc metal?
- catalysts are substances that alter the rate of a reaction.a suitable catalyst would be finely divided platinum.
- Q: Why does the chemical and chemical properties change before and after the reaction?
- At present, the role of the catalyst has not yet fully understood. In most cases, it is believed that the catalyst itself and the reactants participate in the chemical reaction, reducing the activation energy required for the reaction. Some catalytic reactions are due to the formation of a very easy decomposition of the "intermediate", the decomposition of the catalyst to restore the original chemical composition, the original reactant becomes a product. Some catalytic reactions are due to adsorption, adsorption can only be in the catalyst surface of the most active area (called the active center) carried out. The greater the area of the active site, the greater the activity of the catalyst. Reactants such as impurities,
- Q: Thorough explanation pls.
- Catalyst are the substances which increase the rate of reaction. They do not get consumed in the reaction but they participate in intermediate reactions. The catalyst action can be explained as- Providing alternate energy path- Let us suppose that an endothermic reaction need 15 joules of threshold energy to occur. The catalyst will provide them path which needs less energy. Providing Surface- Many reaction may occur slowly because less contact between the molecules/atoms/ions or due to unavailability of proper structure, in this case the catalyst provide surface for carrying the reactions. There are several other actions which mayn't be necessary for you to understand the basic function of catalyst.
- Q: Word editor when playing chemical equation = with the above conditions or how to adjust the size of the catalyst, how to make it centered,
- Open the word - insert - object - WPS3.0 formula - and then select the "label arrow template", you can add a catalyst.
- 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: An important property of the catalyst is that the reaction equilibrium is not changed while increasing the forward reaction rate and the reverse reaction rate. However, because the enzyme for the specificity of the substrate, is not almost every reaction by the enzyme are one way to do it.
- Enzymes, refers to the biocatalytic function of the polymer material, in the enzyme catalytic reaction system, the reactant molecules known as the substrate, the substrate catalyzed by the enzyme into another molecule. Similar to other non-biocatalysts, the enzyme changes the reaction rate by adjusting the Gibbs free energy of the chemical reaction, and most of the enzyme can increase the rate of its catalytic reaction by a million times; in fact, the enzyme is provided with another The activation energy requires a lower route so that more reactive particles produce more effective collisions to produce more kinetic energy. According to the first law of thermodynamics, the kinetic energy obtained by the collision can accelerate the reaction rate by transformation. The enzyme as a catalyst itself is not consumed in the reaction process nor does it affect the chemical equilibrium of the reaction.
