Predicting spontaneity
WebSpontaneity is one that cannot be reversed. However, by using some external agents, you can really reverse the process. The quantity of unpredictability in every system is measured by its entropy. Predicting Spontaneity. In general, the total entropy change is the most important metric for describing the spontaneity of any activity.
