Q:In the chemical reaction, why can the catalyst speed up the reaction rate
Manganese dioxide, copper sulfate, catalytic hydrogen peroxide decomposition.
Q:MnO2: catalyst?
A catalyst changes the RATE of a reaction, not the products. So, yes, you get the same products without the catalyst as you do with the catalyst.
Q:A catalyst?
Always speeds the reaction rate.
Q:What reactions need catalysts?
Reactions that have high Activation Energy need catalysts to speed up reactions. These reactions aren't spontaneous since the reactants do not have enough energy to overcome the activation energy barrier. Catalysts are compounds that speed up reactions by providing an alternative pathway for the reaction. It is a common misconception that catalysts lower the activation energy. It doesn't actually lower the activation energy, instead it provides an alternative pathway with lower activation energy. For example, breakdown of hydrogen peroxide happens in nature but, relatively slowly. When you add a little bit of manganese dioxide, the breakdown happens a lot faster. Another example is, breakdown of glucose in the body. It is facilitated by an enzyme called amylase (or carbohydrase). An industrial example is the use of vanadium pentoxide (V2O5) in the Contact process, where SO2 is converted to SO3 in the presence of V2O5. Hope that helps!
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: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: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 the difference between an enzyme catalyst in a living body and a catalyst in chemistry?
in vivo enzyme activity is regulated in the body, the enzyme activity is regulated control. This is another important feature of the enzyme that distinguishes it from the chemical catalyst. There are many ways to regulate enzyme activity, such as feedback regulation, covalent modification, zymogen activation, allosteric regulation, hormone regulation, and so on.
Q:what is the difference between enzyme and catalyst?
Enzymes and catalysts both affect the rate of a reaction. The difference between catalysts and enzymes is that while catalysts are inorganic compounds, enzymes are largely organic in nature and are bio-catalysts. Even though all known enzymes are catalysts, all catalysts are not enzymes. Moreover, catalysts and enzymes are not consumed in the reactions they catalyze. Catalysts are low molecular weight componds, enzymes are high molecular globular proteins. Catalysts are inorganic, enzymes are organic. Catalyst reaction rates are slower (usually) than enzyme reaction rates. Catalysts are not generally specific - enzymes are VERY specific. Catalysts increase or decrease the rate of a chemical reaction, enzymes are proteins that incrase the rate of chemical reactions & convert the substrate into product. There are 2 types of catalysts - (positive & negative), and the 2 types of enzymes are activation enzymes and inhibitory enzymes. Catalysts are simple inorganic molecules, while enzymes are complex proteins.
Q:Can chemical reaction limits be changed by catalyst or other methods?
You can use heating, pressurization and other methods.
