Gibbs-Helmholtz Equation

The Gibbs-Helmholtz equation relates the change in a substance's free energy (a measure of its potential to do work) to temperature, enthalpy, and entropy. It helps predict whether a chemical reaction or phase change occurs spontaneously at a given temperature. Essentially, it combines thermodynamic properties to determine if a process will happen naturally without external influence. By understanding how free energy varies with temperature, scientists can forecast reaction behaviors and stability of materials in different conditions.
