Abstract
IN a recent publication, Williams and Hinshelwood1 reach the important conclusion that the influence of substituents on the velocity of benzoylation of aromatic amines in benzene solution depends principally on changes in the activation energy, that is, E in the expression k = PZeE/RT. Changes in P, a factor independent of the activation rate, are of much smaller importance as long as the medium is unchanged.
