Abstract

The various contributions to the entropy of activation for metallic diffusion are examined theoretically. In particular, the entropy contribution arising from the altered vibrational frequencies around the saddle point is estimated. It is concluded that negative over-all entropies of activation are theoretically permissible and are likely to arise when the over-all activation energy is small.
