Q:Chemical catalyst system baa?
Can speed up or slow down the reaction rate without participating in the reaction of the material
Q:In the chemical calculation, the quality of the catalyst should not be counted before and after the reaction
It is not the same .. because the quality of the catalyst will not change .
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:What is the analytical principle of chemical adsorbents?
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:Describe the role of a catalyst..........?
a catalyst lowers the activation energy of a reaction. By lowering the activation energy, the internal kinetic energy the reactants become sufficient for the reaction to occur on a much larger scale and thus appear faster. Without the catalyst, you would depend on the statistical probabilities of small numbers of reactant particles having enough internal kinetic energy to overcome the activation barrier. a substrate is merely the substance in the reaction being catalyzed
Q:How do enzymes / catalysts in biology and chemistry in high school stage give different feelings?
I do not know the main high school teachers have done with fresh chicken liver grinding solution and ferric chloride solution compared to the decomposition of H2O2 catalytic efficiency of the experiment, the result is ferric chloride plus H2O2 slowly take the bubble, add fresh chicken cups Quickly take bubbles and liquid spill. Indicating that the enzyme is a catalyst, and the catalytic efficiency is far higher than the inorganic catalyst.
Q:catalyst..........?
H+ is the ion contained in acids.... When acids are dissolved in water (H+)+(H2O)=H3O+ Both are the same......
Q:How does the catalyst for organic synthesis look for?
First of all now the most common way to change the ligand.
Q:why are catalysts never used up during reactons?
Catalysts facilitate the reaction. They might work in several ways. Here is an example: Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process regenerating the catalyst. The following is a typical reaction scheme, where C represents the catalyst, X and Y are reactants, and Z is the product of the reaction of X and Y: X + C → XC (1) Y + XC → XYC (2) XYC → CZ (3) CZ → C + Z (4) Although the catalyst is consumed by reaction 1, it is subsequently produced by reaction 4, so for the overall reaction: X + Y → Z They might also just increase the surface area, thus speeding up the reaction. Example: Coke looses its fizz over time if left with the cork unscrewed. This is because the HCO3 is released as CO2. If you drop a menthos into the coke, it explodes with CO2, because the methos is full of tiny dents in the surface (thus giving it a massive surface area). (i blatantly copied the first example from the wiki)
Q:Why are transition metals more likely to be catalysts?
there are so much catalysts made up of transition metals. because one of the characteristics of transition metals is can be made to catalyst. one of the catalyst that is mostly used is iron fillings which is used as catalyst to make ammonia from nitrogen gas and hydrogen gas.
