WebSep 16, 2024 · Gibbs free energy is a relative measurement of the stability of a phase at Constant Temperature and Pressure. i.e. G=f ( T, P ). G is a state function, so we write it as G=H-TS. For example, at room temperature and at atmospheric pressure H2O exists in Water state but not in ice or vapour state. WebThe reaction can be thermodynamically unstable (favorable) not only due to positive entropy change but also negative enthalpy change, both result in negative free energy. The thermodynamic stability is determined by the difference between the potential energy of products and reactants.

WebFeb 22, 2024 · Feb 22, 2024 at 12:22. Gibbs free energy is basically an indicator of how far and in which direction the equilibrium is pushed. So if the Gibbs free energy is lower (i.e. more negative) that means the equilibrium is pushed towards the product side.
