- Q: Chemical production of iodine and magnesium with water as catalyst!
- In the 250mL three bottles were equipped with spherical condenser and constant pressure dropping funnel, in the condensate tube connected to the anhydrous calcium chloride drying tube. The flask was placed with 1.5 g of magnesium chip and a small tablet of iodine, 10 g of bromobenzene and 30 mL of anhydrous ether were mixed in a constant pressure dropping funnel. First 1/4 of the mixture into the flask, a few minutes later see the magnesium surface of the bubble generated, the solution was slightly cloudy, iodine color began to disappear. If no reaction occurs, use a hot water bath. After the start of the reaction, stir, slowly dropping the remaining bromophene ether solution, dropping the rate to keep the solution was slightly boiling state, after adding, in the water bath to continue reflow 0.5h, magnesium tablets full effect.
- Q: Briefly define a homogenous catalyst? Help please!?
- A homogenous catalyst is in the same phase as the rxn it is catalyzing. Most people think of catalysts as heterogenous: either sold (cat) liquid (rxn) (Raney Ni hydrogenation) or solid (cat) gas phase rxn) (catalytic convertors, NH3 production, SO2 oxidation, nitric acid production) polyethylene synthesis with Ziegler Natta catalysts. (Wikipedia). However starting probably with the Wilkinson hydrogenation catalyst Rh(PPh3)3Cl in 1966 a whole field of homogeneous catalysis has develope where the catayst is in soln. It proved to be a Renaissance for Inorg chem. These catalysts have several advantages over heterogenous catalysts: take place under mild conditions (green chem); the mechanisms are usually understood and can therefore be modified to be extremely specific for a substrate. There have been several Nobel Prizes in this area in the last decade because of their importance in organic synthesis: 2010, 2005, 2001. The one type of homolytic gas phase catalysis rxn I can think of are those that involve a radical chain mechanism: destruction of O3 by Cl? and chlorination (bromination) of alkanes.
- Q: pls give one or two catalysts that are used in the industry for example:Rhodium catalyst in a catalytic converter of a car or the Iron catalyst for making ammoniaTHANKS :)
- i will tell you the hydrogen and carbonmonixide production in indsutry they will use alumina based nickel catalyst for adsorption of gases, at high temperature it will breaks as small molecules like hydrogen, co2, co,ch4, after they will separate them using carbon molecular seives as catalyst. another catalyst for hydrogenation of double bond is copper chromate for sulphur removal from disel and petrol they will use COMOX ( copper and molybdinum catalyst ) after then pass through zinc sulfide with hydrogen gas , the sulfur will removed as a hydrogen sulfide.
- Q: Why are catalysts so effective in small amounts?
- By definition, catalysts serve to accelerate certain chemical reactions, by lowering the activation energy required for them to proceed. They are not consumed by the reaction, which is why they are effective in small amounts.
- 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: Will the catalyst in the chemical reaction be reduced?
- The amount of catalyst in the chemical reaction is not reduced, the catalyst is divided into a positive catalyst and a negative catalyst, the positive catalyst promotes the reaction, and the negative catalyst inhibits the reaction
- Q: how a catalyst can provide a new route in forming the product?
- A catalyst may provide a new route in forming a product. Often the reactants have too much energy and bounce off of each other forming few products. The catalyst may provide a surface where the reactants can settle momentarily in close proximity completing the reaction at an increased rate. The catalyst has been pictured (for illustration only) as a surface filled with grooves and when the reactants settle within the grooves (forming a film?) they are close enough to react rather than bounce off of each other. As such the catalyst facilitates the reaction without being used up in the reaction. The catalyst may become 'poisoned' with other molecules that interfere with the desired reaction and the reactants may have to be relatively pure to protect the catalyst.
- 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: Is the enzyme in the enzyme bigger than gold?
- A biological enzyme is equivalent to a key that opens a complex compound whose importance is that its unique structure or multidimensional shape matches a part of the group. Once these two parts are combined, the specific chemical bond in the group molecule changes as if the lock was opened. When the reaction is completed, the enzyme is released and repeated with the next group, followed by repeated repeats. Many chemical reactions in the normal temperature conditions, the reaction is very slow so that the whole process is difficult to be perceived.
- 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.
