Q:What is the superiority of the catalyst compared to the stoichiometric reagent?
Mildness: means that the chemical reaction catalyzed by the enzyme is generally carried out under relatively mild conditions
Q:What is the maximum impact of the chemical reaction rate?
The catalyst certainly affects the most
Q:Chemical catalyst system baa?
Catalyst is divided into inorganic catalyst and organic catalyst organic reaction generally need more catalyst, such as concentrated sulfuric acid
Q:What happens to this catalyst ?
Only a catalyst? Poor catalyst. Catalysts get very little respect. Folks assume that catalysts don' do anything, yet they magically speed up a reaction without taking part in the reaction. That just isn't the case. Most chemical reactions take place in multiple steps. A catalyst can be a reactant in one step and a product in s subsequent step, thereby giving the impression that it did not react. The catalyst speeds up a chemical reaction by providing an alternate reaction pathway which has a lower activation energy. The lower activation energy means that more molecules will have the energy required to react, and the rate will be greater. So the bottom line is that the catalyst will have appeared not to have reacted, and returns to its original state.
Q:Exemplify the use of green catalysts in green chemistry
The platinum and palladium catalyst in the exhaust pipe of the automobile can catalyze the formation of CO2 and N2 by NO and CO
Q:Chemical reactions in the presence of impurities will cause catalyst poisoning
Catalyst poisoning reaction of raw materials contained in the trace impurities to the catalyst activity, selectivity significantly decreased or lost phenomenon. The nature of the poisoning phenomenon is a trace of impurities and the catalytic activity of the center of a chemical effect, the formation of non-active species. In the gas-solid heterogeneous catalytic reaction is formed in the adsorption complex. One is that if the toxic and active components of the role of weak, can be a simple way to restore the activity, known as reversible poisoning or temporary poisoning. The other is irreversible poisoning, it is impossible to restore the activity in a simple way. In order to reduce the side reaction activity, it is sometimes necessary to allow the catalyst to be selected for poisoning.
Q:Chemical common sense about the catalyst
So that the use of more fully catalyst, the effect is better.
Q:In the catalyst and light conditions to break down the water to get the chemical equation of hydrogen
2H2O = 2H2 ↑ + O2 ↑
Q:What kind of chemical substances can seriously damage the ozone layer, as a catalyst or reactants can be?
Hundreds of years ago the news once the industrial production and emissions of ozone generated less way, the ozone layer will still be thin.
Q:What is the definition and function of the catalyst in chemistry?
The catalyst plays an important role in chemical production. For example: in the oil refining process, the use of high-performance catalyst into gasoline and no other; in the car exhaust treatment process, with the catalyst to promote harmful gas conversion ...
