Q:Brief introduction of enzyme as biocatalyst and general chemical catalyst and its personality
can only change the rate of chemical reaction, do not change the equilibrium point of the chemical reaction, the enzyme itself does not change before and after the chemical reaction (3) can reduce the chemical reaction of the activation energy The
Q:How does the chemical equation calculate the quality of the catalyst?
So it is not included in the calculation
Q:What is the difference between a catalyst and an inducer in a chemical reaction?
The catalyst does not participate in the reaction, but only the carrier of the reaction; the inducer will participate in the reaction
Q:Is it possible for the different chemical reactions to have the same catalyst?
Just as manganese dioxide can catalyze the decomposition of molten potassium chlorate can catalyze the decomposition of hydrogen peroxide, but this is not necessarily the same as the catalyst for the production of the same product, but for the enzyme in order to ensure that the growth of the orderly all have a single Enzymes can only catalyze an organic matter
Q:What is the PTC catalyst in chemistry?
PTC, Phase Transfer Catalyst, phase transfer catalyst PTC is the role of a reaction from one phase to another phase to participate in the reaction to promote a solvent can be dissolved in organic solvents and a solvent insoluble in the ion Reagents react between the two reagents. And this type of reaction is collectively referred to as phase transfer catalytic reaction.
Q:Hydrogen and nitrogen in the high temperature and pressure and catalyst conditions for the synthesi
3H2 + N2 catalyst iron ---> 2NH3 conditions high temperature and high pressure
Q:Name one case in which catalyst poisoning is useful?
alkynes can react with hydrogen in the presence of a catalyst such as palladium to form alkanes, if they catalyst is poisoned you can produce alkenes instead
Q:Can a catalyst react with a reactant?
it can react to start the reaction but should be regenerated during the reaction. if it reacts and not regenerated,then its better to call it reactant instead of catalyst
Q:Could God be Discribed as a Catalyst?
On reflection, I would say no, God can't be described as a catalyst. That would be like calling a farmer who fertilizes his crop a catalyst; whereas it's the fertilizer that is the catalyst. Or it would be like a scientist in a lab adding an enzyme to something to speed a process; and then having us label the scientist as the catalyst. So in the same way, God doesn't seem to be the actual catalyst; maybe the spirit is the catalyst....
Q:Explain, using an example, how a heterogeneous catalyst works?
Because of the production of photochemical oxidants from NOx reacting with hydrocarbons in sunlight Noxer blocks are used to rid the NOx from the surroundings through The titanium dioxide (TiO2) on the bocks absorbs ultra-pink radiation from daylight which excites its electrons to a bigger orbital. On the outside of the crystals of TiO2 a reaction happens between oxygen and a high power electron from the TiO2. O2 + e־ --O2 ־ The excessive vigor electron is then given back to the TiO2 when water then reacts with the oxygen to present H2 O + O2 --H+ + O2 ־ + OH Nitrogen dioxide is oxidised to nitrate ions as a result of the hydroxyl radical being an awfully strong oxidising agent NO2 + OH --H+ + NO3 ־ The superoxide from response 3 also varieties nitrate ions from nitrogen monoxide. NO + O2 ־ --NO3 ־ This nitrate is washed away through rain or combines with the concrete within the block.
