- 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 role of a catalyst in a chemical reaction?
- A catalyst is used to speed up a chemical reaction. It is not consumed during the reaction.
- Q: Will the catalyst change the reaction rate in the chemical reaction?
- Many of the catalysts are specific in varying degrees, and when added to the chemical reaction system that it can catalyze, it must change the rate of chemical reaction, and of course both positively and negatively catalyzed. Chemical reaction rate, it can not be called a catalyst.
- Q: What is catalyst in Science?
- not all catalyst are enzymes. There are biological catalysts as well as non biological ones catalysts are something that speeds up the rate of a chemical reaction without itself getting altered after it. for example an enzyme is a catalyst because it speed up the rate of food digestion (by breaking down food molecules) and doesn't get altered after the reaction.
- Q: Seems intuitive that it wouldn't, but I dunno the qualitative difference between activation energy & Gibbs free energy. I'M TOO LAZY TO GOOGLE I GOTS STUFF TO DO
- A catalyst can change the activation energy not the Gibbs energy. The Gibbs energy is the energy difference between the initial state and final state. A catalyst cannot change that. Imagine you are driving from school to home. How you drive do not change the height difference between the school and your home. However, a catalyst can change your path which can change the routine you drive from school to home. So if there is a hill in between your school and you home, you have the choice to drive through it or drive around. Here is a picture: upload.wikimedia.org/wikipedia/co... A catalyst can change the height of the barrier, but cannot alter the initial or final state.
- Q: Can a catalyst react with a reactant?
- Exactly no. A catalyst just provides a shortcut to a reaction and thats is by combining with the reactant and at end of reaction it splits from the reactant it combined with.if a catalyst reacts then it is not a catalyst
- Q: What is chemical adsorption and its relationship with heterogeneous catalysis
- The catalytic cycle includes five steps: diffusion, chemical adsorption, surface reaction, desorption and reverse diffusion.The chemical adsorption is an important part of the heterogeneous catalysis process, and the adsorption of the reactants on the catalyst surface,
- Q: How are a catalyst and an intermediate similar? How are they different?
- A catalyst speeds up the rate of a reaction by lowering the activation energy barrier which is, presumably, the energy required to achieve the reaction intermediate. Catalysts are also not consumed in the reaction, they are regenerated towards the end. A reaction intermediate is a configuration that a molecule takes prior to achieving it's lowest energy form which would signify the end of the reaction. Intermediate usually are hard to isolate because of the incentive to go to the most stable configuration. How are they different? A catalyst is not a part of the reaction product and it doesn't get consumed. An intermediate in a reaction is transformed into the product. How are they similar? Well, catalysts drive the reaction and make it easier for the reaction for follow through. Since intermediates are high energy and thermodynamics tells us that low energy is favorable, the incentive for a high energy intermediate to drive down to it's stable for can also drive a reaction. I hope that helps. I hope it makes sense.
- Q: Chemical master invited (about catalyst)
- From the thermodynamics can be reaction, and the three formulas can be added to eliminate the intermediate product, indicating that the reaction may occur. The definition of the catalyst is not complete. I am a junior undergraduate student of Jilin University School of Chemistry, according to the definition of the catalyst in the university textbook, the catalyst itself reacts with the reactants to produce unstable intermediates. After the reaction is finished, the intermediate product is explained and the catalyst is reduced. Apparently did not participate in the reaction. So the catalyst to change the course of the reaction, the original reactants to go through a relatively high energy to produce products, there will be a catalyst after a few relatively low energy barrier, so much easier, the reaction rate is greatly accelerated The It can be seen, the catalyst is not no response, but only after the completion of the reaction to restore it. It can also be seen that the amount of catalyst does not matter, and some reactions require the amount of catalyst to be approximately equal to the amount of reactants. Waiting for you to high school and university to further study on this issue will have a more clear understanding of the.
- Q: how do catalysts help in green chemistry?
- Catalysts reduce the energy barrier for reactions, meaning they require less energy to make the forward reaction go. This means less heat, light, or other energy sources are required to perform the same reaction without a catalyst. Also, by definition, a catalyst is not consumed in a reaction and can therefore be recycled many many times before replacement is necessary.
