entropy - KFUPM Faculty List
... Qualitatively, the entropy (S) of a system is a measure of how spread out or how dispersed the system’s energy is. The simplest interpretation of this is how spread out a system’s energy is in space. In other words, for a given system, the greater the volume it occupies, the greater its entropy. ...

Catalysis
Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.
