- 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:What is the reaction of hydrogen peroxide to add manganese dioxide?
- Hydrogen peroxide → water + oxygen (arrows on the manganese dioxide, as a catalyst)
- Q:What is the PTC catalyst in chemistry?
- PTC, Phase Transfer Catalyst, phase transfer catalyst PTC is the role of a reaction from one phase to another phase to participate in the reaction to promote a solvent can be dissolved in organic solvents and a solvent insoluble in the ion Reagents react between the two reagents. And this type of reaction is collectively referred to as phase transfer catalytic reaction.
- Q:In the chemical reaction, why can the catalyst speed up the reaction rate
- Iron catalyzes nitrogen and hydrogen synthesis of ammonia, and no iron reaction occurs almost.
- Q:Is it not the rate to accelerate the addition of the catalyst to the catalyst, and that is why the balance does not move
- If the reaction before the catalyst, you can speed up the reaction rate, that is to achieve the balance required to reduce the time, but to balance the system when the same concentration
- Q:Can the catalyst be a reactant in chemistry?
- There is also a saying that the catalyst participates in the chemical reaction. In a general chemical reaction, the effect of the catalyst is to reduce the activation energy required for the reaction to occur, essentially to turn a more difficult reaction into two, In the second reaction, the catalyst in the first reaction plays the role of the reactant, and the catalyst in the second reaction plays the role of the product, so that the catalyst is not present before and after the reaction Variety.
- Q:what is a catalyst?
- A catalyst is a substance that increase the rate of chemical reaction without itself undergoing any permanent chemical changeb
- Q:Now, i am studying for my biology exam in 3 weeks time...i stumbled upon catalase, and then checked my book its catalyst...now im confused...is there a different among these 2 terms? i think..catalyst is the when a substance brings up or about a chemical reaction without using itself up and then catalase breaks down the toxic by-product of metabolism, hydrogen peroxide, into water and oxygen.Or am i wrong?please explain what is catalyst and catalase in biology or are they the same, just differently?
- A catalyst is a chemical which speeds up a reaction but without being used up in the reaction, so can be used over again. Catalase is an example of an enzyme which are biological catalysts ie speed up reactions in cells. Enzymes are specific and the enzyme catalase breaks down hydrogen peroxide to water and oxygen. A catalyst which also breaks down hydrogen peroxide is manganese dioxide.
- Q:Before and after the reaction, the chemical properties and quality of the water did not change, and the water was the catalyst
- 3HIO + 3H2 = 3H2O + 3HI
- Q:Can some chemical reactions have a variety of catalysts that are correct or wrong?
- Very correct, many reactions can have a lot of catalyst. Such as hydrogen peroxide decomposition can be used manganese dioxide or fe destroy
