- Q:What is the principle of the catalyst? Why can change the rate of chemical reactions and their own without any change
- If you are not asking for a written, you can look at my words. The principle of the catalyst is to make the water muddy. It has to accelerate the chemical reaction, but also slow down the reaction. Catalyst ions into the solution, is to let the solution become muddy, and then should be the reaction of the ion collision probability is large, to speed up the reaction. The substance of the catalyst does not participate in the reaction, so it does not change. Are personal understanding, wrong please more inclusive. Thank you
- Q:Chemical reaction plus catalyst on the △ H no effect
- The catalyst only affects the reaction rate of the substance and increases its activation energy, and the enthalpy change is only related to the initial state of the substance, independent of the reaction process.
- Q:Please make it simple because I need it for school and please give to examples for the second part Thanx :D
- A catalyst is a substance that speeds up the rate of a chemical reaction with itself being chemically unchanged at the end of the reaction. They are useful as they help to lower the minimum amount of energy needed ( also known as activation energy) to start the reaction. Hence, by lowering the activation energy of the reaction, they help to speed up the rate of reaction. For example, in the Haber process for the manufacture of ammonia, the catalyst iron is added to speed up the rate of reaction between hydrogen gas and nitrogen gas. Otherwise, the reaction would have proceeded much more slowly. Another example is the catalyst nickel used in the manufacture of margarine and vanadium (V) oxide for manufacturing sulfuric acid. As catalyst remain chemically unchanged after a reaction, they can be reused again and hence, they are required in minute amounts. An example is the washing powder used in washing clothes, they help to remove food stains by digesting the proteins in food. They can be reused after each reaction and hence, you do not need to add in the whole packet of washing powder but only a few spoonful.
- 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:Can the catalyst be a reactant in chemistry?
- In general, a catalyst is a substance that participates in the intermediate process of chemical reaction and selectively changes the rate of chemical reaction, and its quantity and chemical properties remain substantially constant before and after the reaction, and the catalyst is usually accelerated to Reaction as soon as possible to achieve the role of chemical balance called catalytic role.
- Q:What is the standard for the storage of flammable and explosive chemicals now?
- First, the basic requirements of classification of storage Dangerous goods, variety, complex performance, storage, in accordance with the zoning, classification, sub-section of the principle of special storage, set the number, set the number of fixed warehouses, fixed staff (four) custody. Small warehouses should be classified, divided, sub-stack storage, the performance of each other, fire fighting different items, dangerous dangerous goods and other general dangerous goods, should be stored separately.
- Q:What are the properties of the catalyst (eg, specificity)?
- The definition of a chemical reaction in the chemical reaction can change the chemical reaction rate of other substances, and its quality and chemical properties before and after the reaction did not change the material called catalyst, also known as catalyst. Catalyst in the role of chemical reaction There is also a saying that the catalyst reacts first with one of the reactants and then the two products continue to undergo a new chemical reaction under the original conditions and the reaction conditions of the catalyst reaction are more reactive than the original reaction The reaction conditions of the catalyst have been changed by the reaction of the catalyst by the reaction of the catalyst, that is, the quality and chemical properties mentioned above did not change before and after the reaction.
- Q:Horseradish enzyme catalyzed Luminol chemiluminescence reaction
- Disinfectant ah ~ bleach ah ~ ~ take this kind of thing to wash the blood once something can interfere with Lumino identification. So that want to do bad things must be a good plan. Lumino in the presence of copper, copper alloy, horseradish or some bleach in the presence of fluorescence. So if the scene of the crime was bleached
- Q:What is the microcosmic principle of the catalytic reaction in the chemical reaction?
- The catalyst reduces the activation rate of the reactants by increasing the reactant density of the reaction conditions and making the chemical reaction easier.
- Q:describe a biological catalyst?
- A biological catalyst is the almighty enzyme. An enzyme takes the food that animals eat, yes including you, and breaks the raw stuff into more tangible byte sizes pieces for all the cells of a living organism. So essentially a catalysts is a mover of a biological system. Whole systems such as the apex predator the great bald eagle. I think the whole system catalyst are the decomposer organisms. The little crawlers like shredders and mushrooms. I hope that this helps
