Free energy changes determine if a reaction is endothermic or exothermic. Processes in nature are driven in two directions: toward least MAIN IDEA enthalpy and toward greatest entropy. When these two oppose each other, the dominant factor determines th direction of change. As a way to predict which factor will dominate fora given system, a function has been defined to relate the enthalpy and entropy factors at a given temperature tropy and constant pressure. This combined enthalpy-entropy function is callepd t free energy, G, of the system; it is also called Gibbs free energy. This function simultaneously assesses the tendencies for enthalpy and entropy to change. Natural processes proceed in the direction that lowersthefree energy of a system. Only the change in free energy can be measured. It can be defined in terms of changes in enthalpy and entropy. At a constant pressure and temperature, the free-energy change, AG, of a system is defined as the difference between the change in enthalpy, AH, and the product of the Kelvin temperature and the entropy change, which is defined as TAS. Free Energy Change AGO= AH°- TASO Note that this expression is for substances in their standard states. The product TAS and the quantities AG and AHhave the same umor usually kJ. The units of AS for use in this equation are usually N If AG<0, the reaction is spontaneous. AH and AS in the free-energy equation can have positive or negative values. This leads to four possible combinations of terms.
