- Q:In the chemical reaction, why can the catalyst speed up the reaction rate
- Platinum and rhodium catalyzes the conversion of carbon monoxide and nitrogen oxides to carbon dioxide and nitrogen, which are used in the conversion of automobile exhaust gases, and in most cars.
- Q:What is catalyst in Science?
- A catalyst is a substance that aids a chemical reaction (by doing this increasing the reaction rate) but is not consumed by the reaction. For example, hydrogen peroxide (H2O2) spontaneously decomposes into water and oxygen over time. the addition of manganese dioxide will greatly increase the rate of reaction, but none is consumed.
- Q:how does the amount of a catalyst affect reaction rate?
- theoretically, the more catalyst there is, the faster the rate of reaction. this is because it is bringing more particles together quicker.
- Q:I know that a species that does not appear in the chemical equation may also affect the rate of a reaction - e.g. a catalyst. But does that mean the catalyst can be present in the rate equation, and if so are catalysts always present in the rate equation?
- Yes, a catalyst can be included in a rate law. That's because, most reactions occur in a series of step and the rate is based on the rate determining step, which is the slowest step. A catalyst may be a reactant in the rate determining step, and a product in a subsequent step. Therefore, the catalyst is not included in the overall reaction. But a catalyst need not always be in the rate law. The rate law is usually based on the rate determining step. ========== Follow up =========== In the free response questions on the AP chemistry exam there has been at least one case where a rate law included a catalyst( 2002D). Brown and LeMay always include at least one in their examples, and I always cover this situation when I teach rate laws and mechanisms in AP chemistry. Here is one comment: Other examples of species not in the balanced reaction occurring in the rate law would include catalysis, where a catalyst does not normally appear in the balanced reaction but does appear in the rate law. www.chem.arizona.edu/~salzmanr/48... Consider this generalized reaction which is catalyzed by M A + B --C A + M --Q ... slow Q + B --C ... fast M is the catalyst, and Q is the intermediate. The slow, or rate determining step, depends only on the concentrations of A and M, the catalyst. So even though the overall reaction does not include, M, the rate law does. Rate = k[A][M]
- Q:What is the similarity between enzymes and general chemical catalysts?
- (1) The enzyme is the same in many respects as a biocatalyst and a general catalyst, such as a small amount and a high catalytic efficiency. As with the general catalyst, the enzyme can only change the rate of chemical reaction and does not change the equilibrium of the chemical reaction It is possible to catalyze the activation of a large number of substrates in a short time and to reflect the high efficiency of enzyme catalysis.The enzyme can reduce the activation energy of the reaction (activation) (△ G) during the reaction, but the reaction rate is accelerated and the reaction time is reduced, but the equilibrium constant is not changed. (2) However, the enzyme is a biological macromolecule (1) Enzyme-catalyzed high efficiency: The catalytic effect of the catalyst can increase the reaction rate by 10 ^ 6 ~ 10 ^ 12 times, which is at least several times higher than that of the conventional catalyst. (2) The enzyme catalyst Highly specificity: including specificity of response, substrate specificity, chirality specificity, geometric specificity, etc., that an enzyme can only act on a certain class or a specific substance. Bond, ester bond, peptide bond and so on can be catalyzed by acid-base hydrolysis, but the hydrolysis of these chemical bonds are different, respectively, the corresponding glycosidase, esterase and peptidase, that is, they were specific (3) enzymatic reaction conditions are mild: enzymatic reaction is generally carried out in aqueous solution of pH = 5 ~ 8, the reaction temperature range is 20 ~ 40 ℃
- Q:Is the reaction of the exhaust purification of cars (carbon monoxide and nitrogen
- NO + 2CO = 2CO2 + N2 reaction is exothermic. Conditional catalyst
- Q:In the catalyst and light conditions to break down the water to get the chemical equation of hydrogen
- 2H2O = (light or catalyst) 2H2 ↑ + O2 ↑
- Q:What is the difference between biological enzymes and chemical catalysts?
- The biological enzyme is a class of molecules with moderate molecular weight in the living cells. It is a natural macromolecule catalyst in nature because the enzyme and the reactants are more specific than the reaction of the catalyst with the chemical synthesis of the catalyst (1) High efficiency (2) selectivity good by-product less (3) mild reaction conditions and so on
- Q:What is a catalyst?
- The catalyst can change the reaction rate (either fast or slow), but the catalyst itself is not affected before and after the reaction, that is, the quality of the same, the chemical nature of the same, itself has not changed.
- 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.
