- Q: Why can't catalysts make an unfavorable reaction favorable?Can anyone give me a relatively simple explanation for this?Thank you so much in advance!
- Catalysts, as enzymes, only change the activation energy (the energy the compound needs to gain to transform into products), they don't change the Gibbs energy values of reactants nor products. Therefore, if the delta G of the reaction is positive, it'll still need free energy to complete. They make a reaction complete faster than in normal conditions, but don't change the actual possibility for that reaction to happen. In the human body, a lot of reactions of catabolism have a positive G value and these reactions needs to get energy from other coupled reactions that have a negative value, so the total value is still negative. Many of them use hydrolysis of ATP to provide that energy, as its hydrolysis is about -30 kJ/mol in physiological conditions. I don't know what class you're in to ask this question, so can't really know if this answer is too simple or complicated for u... sorry in advance! Jo?l
- Q: How does catalyst aid a chemical reaction?
- Catalyst just speed up the chemical reaction they don't effect the chemical reaction or its equilibrium.............
- Q: What is the difference between biological enzymes and chemical catalysts?
- Biological enzymes are an environmentally friendly biocatalyst with greater superiority. Such as the reaction speed, processing conditions (such as temperature, PH value, etc.) more moderate, safe and easy to control the operation and can replace the strong alkali and other chemicals. The biological enzymes act only on specific substrates, with little damage to the substrate and the biodegradation of the treated wastewater to reduce water and energy consumption. After more than a century of research by scientists, more than 3,000 known enzymes are generally considered. The application of biological enzymes in the textile industry, initially the application of α-amylase in cotton fabric desizing process, and later developed into the cellulase used in denim washing and bio-polishing process, and now the development of pectinase to the biological scouring Technology, hydrogen peroxide enzyme catalytic decomposition technology, protease in silk and wool fiber applications
- Q: explain how a catalyst can affect the rate of reaction but not be in the overall equation.?
- Catalysts act to increase the rate of reaction, for example by providing an alternative reaction pathway which lowers the activation energy of the reaction i.e. increasing the likelihood of successful collisions between the reactants. However, they are not used up during the course of the reaction, and at the end you have exactly the same mass of catalyst as you started with, unlike the reactant(s), which will be used up to form product(s). So, the overall equation of the reaction does not include the catalyst because it only needs to show the substances which are used up or formed during the course of the reaction i.e. the reactants and products.
- 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: 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.
- MAD = Mutual certain Destruction you could injury us, of direction. yet you could no longer injury us till now we, even from the grave injury you too. we can be lifeless, we understand that. yet you will no longer stay to confirm and revel in it. what would be left of the two one human beings will ought to combat the subsequent war with sticks and stones. 3 skill of dropping the bomb: by skill of airplane, by skill of submarine launch and by skill of ICBM Inter Continental Ballistic Missile. As the two events found out war exchange into certain destruction, neither fairly needed that. We have been given fairly near to nuclear war, exceedingly throughout the Cuba disaster. yet provided that a nuclear war might propose the certain finished destruction of and the U.S. and the u . s . and West + East Europe, it must be prevented. in assessment to on the instant. have been non secular fans already have the bomb (Pakistan) or very near to construct one (Iran) and don't care a rattling concerning the outcomes. Allah will supply! (them with seventy two virgins each and each)
- Q: hey people i need your help about my science lab report...the question on my paper says "what function the catalyst?....please help me on this one...i would really appreciate if you leave me answers....much mahalos to all you folkss...thanks
- A catalyst is a substance used to change the rate of a reaction. If it increases, it is posititve catalyst . Decreases means negative catalyst. If the reactants and catalyst are in same phase, it is homogenous catalysis, otherwise heterogenous. Any reaction to occur, the reactants have to combine to form an intermediate compound and then to product. This requires surpassment of a minimum amout of energy known as Ea- Activation energy. Catalyst decreased the Ea, so that , passing the barrier becomes easy and hence the speeding of the reaction.
- Q: What is the relationship between the catalyst and the chemical reaction? What is the relationship between the enzyme and the catalyst?
- Catalytic, also known as catalyst, is defined in the junior high school stage to be able to change the rate of chemical reactions, and its own quality, composition and chemical properties remain constant before and after chemical reactions. For example, manganese dioxide can be used as hydrogen peroxide (hydrogen peroxide) decomposition of the catalyst. The catalyst is divided into the positive catalyst and the catalyst is used. The positive catalyst contributes to the reaction to move in the positive direction, and the reverse catalyst contributes to the reaction to move in the reverse direction.
- Q: give an example of how a catalysts speeds up the rate of reaction?? thank you!!?
- When making margarine, nickel is used to speed up the process.
- Q: What chemical reactions can water do the catalyst?
- Many solid and solid reactions can be converted into reactions between liquids, which speeds up the reaction rate, and perhaps the water here is the catalyst.
