What is Meant by Gibbs Free Energy?

In Chemistry, the Gibbs free energy, represented by “G” is the energy required to do the work in the chemical reaction. The Gibbs free energy is a thermodynamic property, which is used to predict whether the reaction will happen spontaneously at a constant temperature and pressure. The Gibbs free energy formula is given by

Gibbs Free Energy, G = H – TS


H is called the enthalpy

T is the temperature

S is called the entropy
