We have developed a new functional form that can describe the temperature dependence of liquid phase rate constants for various reactions. The proposed method employs four kinetic parameters, two associated with the gas phase contributions and other two associated with the solvation corrections. These parameters can be fitted to experimental liquid phase rate constants to accurately reproduce the experimental data from room temperature up to the critical temperature of a solvent. The method was evaluated using 14 reactions, and the results reveal that our method showed superior performance at elevated temperatures compared to the Arrhenius equation. The four kinetic parameters have physical meanings and can be also calculated using ab initio methods instead of empirically fitting to the data. A preliminary result implies that the solvation parameters can be computed using the quantum chemistry and COSMO-RS methods to make the 𝑘 liq predictions. Moving forward, future studies should look to collect more experimental data to further evaluate our proposed method and to test whether the kinetic parameters can be accurately calculated using ab initio approaches.
