The enthalpy-entropy relationship of activation was subjected to discussion in connection with the alkaline hydrolysis of 10 barbituric acids. The extrathermodynamic linear equation was derived by using several parameters; the dissociation constant (pK), the 13C shift value [δc(5)] at the 5-position of the ring, and/ or the molecular connectivity index (χ).
