Q:What progress has chemistry brought to our life?
Q:What is the catalyst condition in the chemical equation?
On the middle of the equal sign or arrow above ah ~
Q:What is the catalyst for industrial aluminum electrolysis?
2AlCl3 (melt) = power = 3cl2 + 2al by-product is chlorine
Q:Chemical problems, the selection of catalysts.
Phosphoric acid or sulfuric acid, 280 to 300 ° C, 7 to 8 MPa
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:Chemical master invited (about catalyst)
From the thermodynamics can be reaction, and the three formulas can be added to eliminate the intermediate product, indicating that the reaction may occur. The definition of the catalyst is not complete. I am a junior undergraduate student of Jilin University School of Chemistry, according to the definition of the catalyst in the university textbook, the catalyst itself reacts with the reactants to produce unstable intermediates. After the reaction is finished, the intermediate product is explained and the catalyst is reduced. Apparently did not participate in the reaction. So the catalyst to change the course of the reaction, the original reactants to go through a relatively high energy to produce products, there will be a catalyst after a few relatively low energy barrier, so much easier, the reaction rate is greatly accelerated The It can be seen, the catalyst is not no response, but only after the completion of the reaction to restore it. It can also be seen that the amount of catalyst does not matter, and some reactions require the amount of catalyst to be approximately equal to the amount of reactants. Waiting for you to high school and university to further study on this issue will have a more clear understanding of the.
Q:Does a catalyst have an effect on the Gibbs free energy of a reaction?
A catalyst can change the activation energy not the Gibbs energy. The Gibbs energy is the energy difference between the initial state and final state. A catalyst cannot change that. Imagine you are driving from school to home. How you drive do not change the height difference between the school and your home. However, a catalyst can change your path which can change the routine you drive from school to home. So if there is a hill in between your school and you home, you have the choice to drive through it or drive around. Here is a picture: upload.wikimedia.org/wikipedia/co... A catalyst can change the height of the barrier, but cannot alter the initial or final state.
Q:How does oxygen sensor affect catalyst converter?
With a four cylinder engine, the code definition should have read: B1S1 (for the upstream sensor responsible for fuel/air ratio monitoring) or B1S2 (for the sensor downstream of the catalytic converter, which only monitors that part). If you changed the front (S1) sensor and you still have a code for it, save your old sensor as there may be nothing wrong with it. If the code is for the O2 sensor heater, check your fuses. If not, the code is probably a symptom of another problem, such as a misfire, restricted fuel filter or intake air leak. Is this the same code you got previously? Did you install a direct-fit replacement or a universal sensor that had to be configured for your honda's wiring connector?
Q:What is the microcosmic principle of the catalytic reaction in the chemical reaction?
The catalyst reduces the activation rate of the reactants by increasing the reactant density of the reaction conditions and making the chemical reaction easier.
Q:Related to the issue of chemical catalysts, experts into the !!!
This problem is not easy to answer, the principle of manganese dioxide catalytic hydrogen peroxide I have not learned, but I have also considered, I think so, hydrogen peroxide and manganese dioxide first combination, the formation of permanganic acid, permanganic acid is a Very special acid is indeed present, it can not be stable under normal conditions, it will be further decomposition, the formation of manganese dioxide, oxygen and water
