Biology 1510/1511 Georgia Tech School of Biology Fall 2008 Energy and Thermodynamics Free energy (G): maximum amount of energy that can be extracted from a chemical system. G = H – TS H = enthalpy T = absolute Temp S = entropy A reaction will occur spontaneously only if ∆G < 0, that is if energy is released by the system. ∆G = ∆H – T∆S < 0
