For an electron donor/acceptor pair at 298 K, ket = 2.02 × 105 s−1 and ΔrG⦵ = −0.665 eV. The standard reaction Gibbs energy changes to ΔrG⦵ = −0.975 eV when a substituent is added to the electron acceptor and the rate constant for electron transfer changes to ket = 3.33 × 106 s−1. Assume that the distance between donor and acceptor is the same in both experiments and estimate the values of Het(d) and ΔER.
