10/1/09 Chapter 10 Spontaneity, Entropy, & Free Energy The first law of thermodynamics does not tell us if a reaction is spontaneous. A spontaneous reaction is a reaction has the potential to proceed on its own accord Examples: 1)Ice spontaneously melts at Room Temperature Define a new Thermodynamic function (S) Entropy(S): is a measure of the disorder of a system Highly disordered system High Entropy Entropy is closely dissociated with probability Nature spontaneously towards states that have the highest probability of existing
