From Wikipedia... Gibbs energy

Type of thermodynamic potential

In thermodynamics, the Gibbs free energy is a thermodynamic potential that can be used to calculate the maximum amount of work, other than pressure–volume work, that may be performed by a thermodynamically closed system at constant temperature and pressure. It also provides a necessary condition for processes such as chemical reactions that may occur under these conditions. The Gibbs free energy is expressed as where:

  • is the internal energy of the system
  • is the enthalpy of the system
  • is the entropy of the system
  • is the temperature of the system
  • is the volume of the system
  • is the pressure of the system.
