What is Gibbs Free Energy?

Gibbs free energy (ΔG) is a thermodynamic quantity used to predict whether a chemical reaction will occur spontaneously. It combines enthalpy (ΔH), entropy (ΔS), and temperature (T) into a single value. The equation for Gibbs free energy is:

ΔG = ΔH - T × ΔS

If ΔG is negative, the reaction is spontaneous. If it is positive, the reaction is non-spontaneous. This concept is crucial in understanding chemical reactions and biological processes.
