The symbol G (?G) stands for the change in a system's Gibbs free energy during a chemical or physical process.

The energy present in a system that may perform beneficial work at constant temperature and pressure is known as Gibbs free energy, which is a thermodynamic property.



The following equation can be used to compute the Gibbs free energy change, ?G:

?G = ?H - T?S

where ?H is the change in enthalpy of the system, T is the temperature in Kelvin, and ?S is the change in entropy of the system.
