Gibbs energy formula in electrochemistry
In thermodynamics, the Gibbs free energy (or Gibbs energy as the recommended name; symbol ) is a thermodynamic potential that can be used to calculate the maximum amount of non-volume expansion 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 chemic… WebJun 1, 2024 · G is used to represent Gibb’s free energy. The SI units of Gibb’s free energy are Joules or Kilojoules. Gibbs free energy is the most work a closed system can collect. …
