In industrial production, the large amount of catalyst used frequently, the catalyst that does not change theoretically may sometimes change into another substance, which is the so-called poison of catalyst,
The catalyst plays a role in a variety of ways that are likely to temporarily alter the chemical changes associated with the reactants themselves, and may also only help to adsorb the physical changes in the reactants, but the reaction eventually becomes its own form The
The catalyst itself reduces the energy barrier (Ea, activation energy) of the chemical reaction, making the reaction easier.
The catalyst can change the reaction rate (either fast or slow), but the catalyst itself is not affected before and after the reaction, that is, the quality of the same, the chemical nature of the same, itself has not changed.
