Chapter 66: How does Energy Change in Spontaneous Process 4/1/16 66.1 What is a Spontaneous Process Spontaneous process changes that are chemically or physically possible under specified conditions without an external energy cource Spontaneous doesn’t mean it will happen in a reasonable amount of time o Ex. rusting of an iron nail spontaneous but very slow It has directionality with respect to time Directionality is a psychological indicator of a reaction over time Spontaneous can depended on temperature 66.2 What is Entropy Second law of thermodynamics in a spontaneous process, energy changes from being localized to being spread out, more organized less organized First law of thermodynamic
