Q:Name one case in which catalyst poisoning is useful?
Usually, catalyst poisoning is undesirable as it leads to a loss of usefulness of expensive noble metals or their complexes. However, poisoning of catalysts can be used to improve selectivities of reactions. In the classical Rosenmund reduction of acyl chlorides to aldehydes, the palladium catalyst (over barium sulfate or calcium carbonate) is poisoned by the addition of sulfur or quinoline. This system reduces triple bonds faster than double bonds allowing for an especially selective reduction. Lindlar's catalyst is another example — palladium poisoned with lead salts. As described by its inventor,[1][2] the catalyst is prepared by reduction of palladium chloride in a slurry of calcium carbonate followed by adding lead acetate. By this approach, one obtains a catalyst with a large surface area. Further deactivation of the catalyst with quinoline enhances its selectivity, preventing formation of alkanes. An example of alkyne reduction is the reduction of phenylacetylene to styrene.[1] en.wikipedia.org/wiki/Lindlar%27s...
Q:Can you describe at least 4 ways a catalyst can lower the activation energy of a reaction?
To see how a catalyst accelerates the reaction, we need to look at the potential energy diagram shown below which compares the non-catalytic and the catalytic reaction. For the non-catalytic reaction, the figure is simply the familiar way to visualize the Arrhenius equation: the reaction proceeds when A and B collide with succificient energy to overcome the activation barrier. The change in Gibbs free energy between reactants, A + B, and the product P is delta G. The catalytic reaction starts by bonding of the reactants A and B to the catalyst, in a spontaneous reaction. Hence, the formation of this complex is exothermic and the free energy is lowered. There then follows the reaction between A and B while they are bound to the catalyst. This step is associated with an activation energy; however, it is significantly lower than that for the uncatalyzed reaction. Finally, the product P seperates from the catalyst in an endothermic step. The energy diagram illustrates 4 ways the catalyst works : The catalyst offers an alternative path for the reaction that is energetically more favorable The activation energy of the catalytic reaction is significantly smaller than that of the uncatalyzed reaction; hence the rate of the catalytic reaction is much larger The overall change in free energy for the catalytic reaction equals that of the uncatalyzed reaction. Hence, the catalyst does not affect the equilibrium constant for the overall reaction. A catalyst cannot change the thermodynamics of a reaction but it can change the kinetics. The catalyst accelerates both the forward and the reverse reaction to the same extent. In other words, if a catalyst accelerates the formation of product P from A and B, it will do the same for the decomposition of P into A and B.
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:Why the amount of catalyst is too small will make the chemical reaction rate slowed down
The catalyst changes the reaction rate by changing the reaction pathway and reducing the activation energy of the reaction.
Q:catalyst efficiency low bank 1?
The question was for bank 1 and the code is for bank2.Toadyboy is correct.Follow his lead.
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 chemical reaction is added to the catalyst in order to slow down the reaction
Edible oil added 0.01% to 0.02% gallate n-propyl ester, you can effectively prevent rancidity
Q:What is the difference between a catalyst and an oxidizing agent?
A catalyst alters the rate of a reaction without being used up in the reaction. An oxidising agent oxidises other compounds, the agent itself being reduced in the process.
Q:In the chemical calculation, the quality of the catalyst should not be counted before and after the reaction
Half is not easy to save trouble
Q:The greater the chemical adsorption strength, the catalyst activity changes
If the adsorbent is a reactant, then the better the adsorption capacity of the better catalytic effect; but the catalyst surface of the product will generally have adsorption, if this effect has become very strong, then desorption The process will become difficult, the catalytic effect will decline; the other one, if the adsorption of other substances, such as the reaction may produce a reaction or the catalyst will poison the material, it is greatly detrimental to the catalytic effect. The effect is to be controlled in a suitable optimum range for superior, and preferably to be selectively adsorbed.
