Catalysis
is the process of increasing the rate of a chemical reaction by adding a
substance known as a catalyst , which is not consumed in the catalyzed
reaction and can continue to act repeatedly.Because of this , only very
small amounts of catalyst are required to alter the reaction rate in
principle.
In
general , chemical reactions occur faster in the presence of a catalyst
provides an alternative reaction pathway whit a lower activation energy
than the non-catalyst mechanism. In catalyzed mechanisms , the catalyst
usually reacts to form a temporary intermediate , which than
regenerates the original catalyst in a cyclic process. A substance which
provides a mechanism with a higher activation energy does not decrease
the rate because the reaction can still occur by the non-catalyzed
route. An added substance which does reduce the reaction rate is not
considered a catalyst but a reaction inhibitor.
