CATALYST CATACLISMO

DEFINE: Catalysis is the change in rate of a chemical reaction due to the participation of a substance called a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. A catalyst may participate in multiple chemical transformations. Catalysts that speed the reaction are called positive catalysts.

think about it

a knife as a catalyst.... draw you own conclusion about what that could speed up!
