Free Energy Gibbs Free Energy
What is Free Energy Gibbs Free Energy?
Gibbs free energy (G) is a thermodynamic potential that measures the maximum reversible work a thermodynamic system can perform at constant temperature and pressure. It combines enthalpy and entropy into a single criterion for spontaneity: G = H − TS. Changes in Gibbs free energy (ΔG) are used to predict whether chemical reactions and phase transitions will occur spontaneously under given conditions.
