Gibbs Free Energy
Gibbs Free Energy is a thermodynamic potential that measures the maximum amount of reversible work that can be performed by a system at a constant temperature and pressure. It is used to predict the spontaneity of a reaction and to determine the equilibrium state of a system.

Gibbs Free Energy and Chemical Reactions
In a chemical reaction, the change in Gibbs Free Energy (ΔG) is equal to the difference between the Gibbs Free Energies of the reactants and products. If ΔG is negative, the reaction is spontaneous and will proceed in the forward direction. If ΔG is positive, the reaction is non-spontaneous and will not proceed in the forward direction without an input of energy.
ΔG can be calculated using the following equation:
ΔG = ΔH - TΔS
where ΔH is the change in enthalpy, T is the temperature in Kelvin, and ΔS is the change in entropy.
Gibbs Free Energy and Equilibrium
At equilibrium, the Gibbs Free Energy of a system is at a minimum. This means that there is no net change in the Gibbs Free Energy and the system is in a state of balance. The equilibrium constant (K) for a reaction is the ratio of the activities of the products to the activities of the reactants at equilibrium. K is related to ΔG by the following equation:
ΔG = -RTlnK
where R is the gas constant.
Applications of Gibbs Free Energy
Gibbs Free Energy is used in a wide variety of applications, including:
- Predicting the spontaneity of reactions
- Determining the equilibrium constant of reactions
- Calculating the work done by a system
- Designing chemical processes
- Understanding the behavior of materials
