Thermodynamics, Entropy, Free Energy, and the Direction of Chemical Reactions Chapter 20 beings with an introduction to the 2 ndLaw of Thermodynamics, but don not forget that the first law of thermodynamics is essentially energy cannot be created or destroyed, but rather is conserved. I. The Second Law of Thermodynamics: Predicting Spontaneous Change  A spontaneous change occurs under specified conditions, and does not require a continuous input of energy—think of a fire. o Under certain conditions it is very easy to start a fire, and then the fire will continue to burn spontaneously even though you are not putting more energy into it.  NOTE that when we say “spontaneous” we mean that if the proce
