Q:PT / AL_203 catalyst and the main chemical use
I have a friend working in Hunan, inquire, as if the piece of PT has the most advanced equipment ,,, you can hit 114 inquiries ~!
Q:What is the catalyst in the end?
You said the chemical catalyst or Ati graphics card catalyst? If the above is enough to explain the above, if it is the latter, that is, the meaning of the graphics card, Ati's graphics drive like a catalyst
Q:can you guys help me by listing all the catalysts?
copper nickel zinc common catalysts are solid acids such as the silicas, alumina, and zeolites it depends on the reaction
Q:Co and No form a chemical equation for Co2 and No2 under the action of a catalyst
Write the catalyst on the horizontal line, where NO is the oxidant and CO is the reducing agent
Q:Explain how a catalyst may increase the rate of chemical reaction?
A catalyst speeds up the reaction by lowering the energy needed for a reaction to occur.
Q:CO and NO react under the action of a catalyst to generate chemical formulas for CO2 and N2.
2CO + 2NO = catalyst = 2CO2 + N2
Q:how do catalysts work?
Catalysts lower the activation energy of a given chemical reaction, thus speeding it up
Q:How does the catalyst generally add to the organic chemical reaction?
In the case of heterogeneous catalysis, the specific surface of the catalyst, in addition to the activity of the catalyst, is an important factor in determining the reaction rate, which means that the specific surface for catalysis is large and the reaction is as fast as the whole. So the overall principle in understanding the activity of the premise of the catalyst, would like to quickly add a little more.
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 makes an enzyme a catalyst?
A catalyst is a substance that speeds up a chemical reaction, by lowering the activation energy, and which is not consumed or permanently altered in the process (such that after it has catalyzed the reaction once, it can catalyze the reaction again, and again -- multiple turnover). Catalysts can be as simple as a monatomic ion; they can also be inorganic compounds, non-biological organic molecules, or biological molecules. Biological catalysts are enzymes. Enzymes meet all of the criteria for being a catalyst (speed up chemical reactions, by reducing the activation energy, and are not permanently altered).
