Abstract
IT has been frequently observed that in some series of kindred reactions the activation energy of the process appears to be functionally related to the respective frequency factor A. For example, when one investigates a reaction taking place in various solvents, one often finds that E (the activation energy) and A change in the same direction. Such behaviour might indicate that the variation in the nature of the solvent affects the degree of solvation of the transition state, and consequently the activation energy and the entropy of activation (that is, A) in the same direction.
