TL;DR: In this article, a detailed derivation of the absolute rate theory expression for a bimolecular gas phase reaction is presented with special attention to clearly explaining all assumptions, where conformations of the reactant pairs lie close to the critical surface and have close to their equilibrium populations.
Abstract: A detailed derivation of the absolute rate theory expression for a bimolecular gas phase reaction is presented with special attention to clearly explaining all assumptions. In the case of activated complexes, conformations of the reactant pairs lie close to the critical surface and have close to their equilibrium populations. (DDA)
