Which of the following is NOT a factor influencing the Gibbs energy of complex formation?

The influence of factors on the Gibbs energy of complex formation is crucial for understanding coordination chemistry. The Gibbs energy change (ΔG) is affected by a variety of factors that relate to the stability and formation of complexes.

The temperature of the reaction plays a significant role in the Gibbs energy of formation, as described by the Gibbs-Helmholtz equation, which illustrates how temperature, enthalpy, and entropy changes are interrelated. An increase in temperature can shift the position of equilibrium for the formation of a complex, potentially affecting the Gibbs energy. As such, temperature is indeed a documented factor influencing Gibbs energy.

On the other hand, the effects of solvent competition, rearrangement of substituents, and steric repulsion are more specific interactions that can influence the stability and propensity for complex formation. Solvent competition can impact the solubility and availability of reactants, rearrangement of substituents can influence the complex's spatial arrangement and stability, and steric repulsion pertains to the spatial hindrance that can affect how easily reactants can approach one another for complex formation.

In summary, while the temperature certainly influences Gibbs energy, the other choices represent interactions that can specifically affect the complexation process. Therefore, the only option that
