An alternative functional form that can describe the temperature dependence of 𝑘 liq with minimal empirical parameters is needed. Previously, we have developed a correlation to predict the solvation free energy of a species from around 250 K up to the critical temperature of a solvent with only two solvation properties . The correlation was able to provide accurate predictions for a variety of solvent-solute pairs only based on the solvation free energy and solvation enthalpy at 298 K and the solvent's density. In this work, we apply the same correlation to estimate the solvation free energies of the reactants and TS of a reaction, hence estimating the ΔΔ𝐺 ‡ solv across a range of temperatures. Our proposed method only needs two parameters to express the temperature dependence of ΔΔ𝐺 ‡ solv , which can be easily fitted to experimental data or potentially calculated using ab initio methods. The devised method can be combined with the Arrhenius equation to accurately reproduce the experimental rate constants of diverse liquid phase reactions for a wide range of temperature.
