Conclusions 1.An equation taking the form of a linear relationship between free energies and describing the effect of the pressure on the rate constants of Diels-Adler reactions has been proposed. The equation proved to be applicable in 31 out of 34 reactions tested (two of the reactions were classified as borderline).2.The activation volumes ?Vo? have been calculated for all the reactions tested.3.An hypothesis that the value of ?Vo? is governed mainly by a decrease in the free volume rather than in the volume of the particles themselves, has been advanced. |
