The Gibbs free energy of a system changes with temperature, as defined by the thermodynamic equation ΔG = ΔH - TΔS, meaning it is not constant at a given temperature if the temperature changes, and temperature variations alter the Gibbs energy of formation.

The analysis

The claim states that the Gibbs standard free energy remains constant at a given temperature, but frames it confusingly or incorrectly regarding temperature dependency. Specifically, Gibbs free energy is a function of temperature ($ΔG = ΔH - TΔS$), meaning it varies when temperature changes. The retrieved papers (such as [4], [5], and [6]) explicitly examine the temperature dependence of Gibbs free energy and thermodynamic parameters, demonstrating that Gibbs energy changes with temperature. Therefore, the claim that it remains constant across varying temperatures is refuted.
