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:Explain how catalysts help to reduce costs in industrial processes !?Thanks: Catalysts are efficient at converting starting materials to the final products. Since catalysts convert these materials to the product faster, less energy will be used, and often less other materials will be used to complete the process. Both will save the company save time and money. Not to mention the catalyst can be reused, often hundreds of times before it needs to be replaced. Hope that helps!

Q:1. Catalysts can help to bring the reactants together in the correct orientation2. The chemical formula of a catalyst is written on the left hand side (reactant) side of an equation.3. Catalysts can provide a surface on which the reaction occurs.4. Catalysts increase the activation energy.5. Catalysts increase the magnitude of the equilibrium constant, thus favoring product formation.6. &quot;Enzymes&quot; are biochemical catalysts.7. Catalysts increase the rate of a reaction.8. Catalysts are slowly used up during the reaction and need to be replaced.: 7 is definetly true

Q:i keep messing up on those 2 simple things haha i would apprecaite some help.: enzymes help biochemical reactions proceed at a faster rate than normal in a physiological system, catalysts or sometimes referred to as subunits, metals and other ligands, bind enzymes, and can have a positive and negative effect on the rate of a reaction. search them on wikipedia!

Q:What is the catalytic efficiency of ordinary chemical catalysts?: Different reactions, with the same catalyst, the catalytic efficiency is different. The same reaction, with different catalysts, the catalytic efficiency is also different

Q:What is the analytical principle of chemical adsorbents? How about the number of active catalyst centers tested?: What do you mean by the chemical adsorber? BET is the use of the surface of the uneven force field, but the inert gas at low temperature in the surface adsorption. TPD, TPR is the number of active centers that can be measured by the technique of desorption and reduction between specific gases and catalysts as the temperature increases. If the active site is a reduced position, H2-TPR can be used. If the active site is acidic, NH3-TPD can be used, but also the method of alkali titration.

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:A catalyst elevates the rate of a reaction by?: Catalysts work by providing an (alternative) mechanism involving a different transition state and lower activation energy. Consequently, more molecular collisions have the energy needed to reach the transition state. Hence, catalysts can enable reactions that would otherwise be blocked or slowed by a kinetic barrier. The catalyst may increase reaction rate or selectivity, or enable the reaction at lower temperatures. This effect can be illustrated with a Boltzmann distribution and energy profile diagram. Take a look!

Q:Why the catalyst is required to have a large surface area and a rich pore structure: Because of the chemical reaction, the larger the contact area, the faster the reaction rate, therefore, the catalyst has a large surface area or pore structure, are to increase the contact area of the catalyst and reactants.

Q:The catalyst can change the chemical reaction process, why is it wrong?: Clear catalyst is to change the reaction rate, and some of the catalyst in the reaction is to speed up the reaction rate, and some reactions in the catalyst is to slow down the reaction rate. The catalyst changes the rate of chemical reaction and can not be said to change the course of the reaction
