Q:What is the catalyst condition in the chemical equation?: On the middle of the equal sign or arrow above ah ~

Q:The concept of catalyst in high school chemistry: Since the catalyst can only change the chemical reaction rate, the catalyst can not increase the mass of the product. The quality of the product depends only on the quality of the reactants.

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:How are a catalyst and an intermediate similar? How are they different?: A catalyst speeds up the rate of a reaction by lowering the activation energy barrier which is, presumably, the energy required to achieve the reaction intermediate. Catalysts are also not consumed in the reaction, they are regenerated towards the end. A reaction intermediate is a configuration that a molecule takes prior to achieving it's lowest energy form which would signify the end of the reaction. Intermediate usually are hard to isolate because of the incentive to go to the most stable configuration. How are they different? A catalyst is not a part of the reaction product and it doesn't get consumed. An intermediate in a reaction is transformed into the product. How are they similar? Well, catalysts drive the reaction and make it easier for the reaction for follow through. Since intermediates are high energy and thermodynamics tells us that low energy is favorable, the incentive for a high energy intermediate to drive down to it's stable for can also drive a reaction. I hope that helps. I hope it makes sense.

Q:What is the catalyst for industrial aluminum electrolysis?: 2AlCl3 (melt) = power = 3cl2 + 2al by-product is chlorine

Q:Chemical questions: "CO2 and H2 in the catalyst conditions have a reaction, the reaction of the chemical equation is": CO2 + H2 = CO + H2O (conditions: catalyst, generally requires heating, and reversible)

Q:Is there a catalyst in the chemical shop?: If it is like vanadium pentoxide, which catalyzes sulfur dioxide, do not sell it because vanadium is highly toxic and most of the catalyst is expensive

Q:The role of catalyst in chemical reactions: Negative catalysts can be used to control the reaction rate (such as some reaction too fast, instantly release a lot of energy caused by danger, you can join), common is the antioxidant

Q:Describe the role of a catalyst and a substrate in a chemical reaction.: 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
