The linear expressing the dependence of the rate of applies to the reference solvent (ethanol–water, 80:20, v/v) and to the solvent s, both at . The parameter is characteristic of the substrate and is assigned the value unity for tert-butyl chloride. The value is intended to be a quantitative measure of the where is the its susceptibility parameter. The equation has also been applied to reactions other than
free energy
relation: solvolysis
of a substrate on ionizing power
of the solvent. The rate constant
ionizing power
of the solvents. The equation was later extended to the form: nucleophilicity
of the solvent and solvolysis
