SUMMARY
The discussion clarifies the distinction between Gibbs free energy (ΔG) and activation energy in chemical reactions. Gibbs free energy is defined as a thermodynamic quantity that indicates the spontaneity of a reaction, represented by the equation ΔG = ΔH - TΔS. In contrast, activation energy is the energy barrier that must be overcome for a reaction to proceed, denoted by the energy difference between the transition state and the reactants' enthalpy. The relationship between Gibbs free energy and enthalpy is illustrated through the equation ΔG = ΔH - TΔS, emphasizing the role of temperature and entropy in determining reaction feasibility.
