Q:Will the chemical catalyst not reduce that?
Why is it done? Although the catalyst does not react chemically, the catalyst itself is deteriorated and is not always used
Q:Hydrogen and oxygen in the role of the catalyst can do the chemical formula of aviation fuel?
Do not be irresponsible, rocket fuel is hydrogen peroxide. H2 + O2 = H2O2 (catalyst)
Q:CO and NO in what the role of the catalyst under the chemical reaction
Palladium Pd, platinum Pt as a catalyst
Q:Comparison of biocatalysts with chemical catalysts!
(1) The chemical reaction catalyzed by the biological enzyme is generally carried out under relatively mild conditions. (2) The enzyme has the highest activity at the optimum temperature and pH, and the temperature of the biocatalyst is more moderate. And PH high or low, the enzyme activity will be significantly reduced.In general, the animal in the enzyme the optimal temperature between 35 ~ 40 ℃; plant enzyme in the optimal temperature between 40 ~ 50 ℃; animal body Of the enzyme most of the most suitable pH between 6.8.0, but there are exceptions, such as the optimal pH of pepsin 1.5; plant enzymes in the most suitable pH between 4.6.5. (3) acid, Or the temperature is too high, the enzyme structure will be destroyed, so that the enzyme permanently inactivated .0 ℃ or so, the enzyme activity is very low, but the spatial structure of the enzyme is stable, at the appropriate temperature of the enzyme activity can be increased The
Q:Why are transition metals more likely to be catalysts?
there are so much catalysts made up of transition metals. because one of the characteristics of transition metals is can be made to catalyst. one of the catalyst that is mostly used is iron fillings which is used as catalyst to make ammonia from nitrogen gas and hydrogen gas.
Q:Related to the issue of chemical catalysts, experts into the !!!
There are bubbles produced
Q:What is the reaction in chemistry?
Industrial production of ammonia, ethanol, industrial synthesis of ammonia, ethanol catalytic oxidation, acetaldehyde oxidation into acetic acid, ethyl acetate preparation, the transformation of automobile exhaust, benzene substitution reaction and addition reaction, some other addition reaction of hydrocarbons, Ethanol dehydration to produce ethylene and so on
Q:Which of the following are true about catalysts?
1, 3, 5, 6, 7. 2 is incorrect, catalysts are written above the reaction arrow. 4 is incorrect, catalysts decrease the activation energy thus increasing the rate of reaction (see 7) 8 is incorrect, catalysts are not used up (or if they are, they are also regenerated by a different reaction so that they maintain a constant concentration). edit: about 5, yes i think the answer below is correct, 5 is false actually. catalysts speed up both the forward and the reverse reaction so the equilibrium constant is unchanged. however, 1 is true i think: catalysts can provide a lower energy pathway by way of bringing the reactants together in the correct orientation (rather than random orientations).
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:Will the catalyst be able to increase the rate of chemical reactions?
In general, the catalyst has a positive catalyst (i.e., accelerates the reaction rate) and a negative catalyst (i.e., reduces the reaction rate), and generally does not specifically refer to both the positive catalyst.
