WebGibbs free energy, denoted \(G\), combines enthalpy and entropy into a single value. The change in free energy, \(\Delta G\), is equal to the sum of the enthalpy plus the product of the temperature and entropy of the system. \( \Delta G\) can predict the direction of the chemical reaction under two conditions: constant temperature and WebWhichever one has the lowest free energy, of course! And that depends on temperature. At very low temperature, \ ... That causes the liquid phase to have lower free energy than the solid phase, so a little water melts. As it melts, kinetic energy is converted to potential energy as hydrogen bonds are broken, ...
WebJun 9, 2024 · The free energy change of a reaction is a mathematical combination of the enthalpy change and the entropy change. \[\Delta G^\text{o} = \Delta H^\text{o} - T \Delta S^\text{o}\] The symbol for free energy is \(G\), in honor of American scientist Josiah Gibbs (1839 - 1903), who made many contributions to thermodynamics.
