Predicting the rates of chemical reactions occurring in solution, particularly in the absence of experimental data, is a challenging task. However, common families of reactions occur in both the liquid-phase and gas-phase; for example, gas-phase combustion of hydrocarbon fuels will be dominated by hydrogen abstraction reactions, as will the low temperature, liquid-phase oxidation of fuels by exposure to the atmosphere. Since these reaction types also occur in the gas phase and are sometimes better studied, it can be advantageous to modify these known gas phase reaction rates rather than predicting the solution phase kinetics directly.
