پاورپوینت کاتالیزور به زبان لاتین
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.
