SUMMARY
The Helmholtz and Gibbs free energy are primarily utilized in the context of chemical reactions and phase transitions. In phase transitions, the Gibbs function remains constant due to the conditions of constant temperature and pressure, leading to the relationship ΔH = Q and ΔS = Q/T. The analysis confirms that during a phase transition, the change in Helmholtz free energy (ΔA) equals zero, as derived from the equation ΔA = ΔH - TΔS. This indicates that these thermodynamic potentials are not commonly applied outside of these specific scenarios.
