The equilibrium constants, the second-order rate constants, and the activation parameters have been determined for the proton transfer from di-(4-nitrophenyl)methane to ethoxide ion in a series of mixed solvents containing various amounts of acetonitrile in ethanol. The quantities have been interpreted in terms of the general postulates of the Miller–Parker theory of solvation effects.
