✦ Synopsis

A unified point of view for activated chemical reactions in gas and condcnscd phases is discussed. Contact is made with mechanical and dynamical formulations (c.g., simulations based on classical trajectories) as well as with statistical theories of reaction rates and theu thermodynamic formulations. This approach 1s consistent with existmg theories but also covers additional physico-chemical sttuatlons which we suggest are common. Three examples are reviewed: acttvated atom exchange in solution, activated desorption from a surface and dissociation of clusters, which demonstrate that dynamical manifestations such as selective energy requirements can be observed in many-body systems.
