Q:Can the catalyst be a reactant in chemistry?
In the chemical reaction can change the chemical reaction rate of other substances (both improve and reduce), and its own quality and chemical properties in the chemical reaction before and after the material did not change called catalyst. [From the definition of reactants. To
Q:how heterogeneous catalyst work?
The Reduction Catalyst The reduction catalyst is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the NOx emissions. When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. For example: 2NO =N2 + O2 or 2NO2 =N2 + 2O2 The Oxidization Catalyst The oxidation catalyst is the second stage of the catalytic converter. It reduces the unburned hydrocarbons and carbon monoxide by burning (oxidizing) them over a platinum and palladium catalyst. This catalyst aids the reaction of the CO and hydrocarbons with the remaining oxygen in the exhaust gas. For example: 2CO + O2 =2CO2
Q:Which branch of chemistry or what specialty can study the catalyst
Physical chemistry: catalyst surface structure, catalytic mechanism and catalytic reaction process
Q:Please help - question about catalysts !?
they reduce the activation energy of a specific chemical reaction, which in turn reduces the temperature at which a reaction will occur at any significant rate (and therefore fuel costs) while generally making the reaction occur faster. In general, if you can catalyze a reaction, you can get away with using less robust equipment because you don't need as much energy.
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:When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
The habit of writing is not to write the catalyst involved in the equation, it is usually written in the equation above the equal or below
Q:High school chemistry, catalyst activation energy map
Catalytic reaction is the reaction of the first reaction with the catalyst or attached to the catalyst to form intermediates, and then further reaction to produce products and catalysts, so the amount of catalyst in theory is the same! The activation of these two processes can be reduced! So there will be two peaks! Can be simplified as a peak!
Q:what function does catalyst have?
The answer above mine is correct. You should also note that a catalyst does not take part in the reaction: it just makes things easier as the previous person said.
Q:The quality and nature of the catalyst before and after the chemical reaction did not change this sentence wrong?
There is no wrong catalyst just to speed up the reaction
Q:Catalyst - Can it decrease the rate of a reaction?
no, by defintion the catalyst speeds up the reaction.
