Abstract
The spontaneous aquation reaction of Co(NH3)5Br2+ was enhanced by addition of sodium polyethylenesulfonate, an anionic polyelectrolyte. The volume of activation was negative in the absence of the macroions and positive in their presence. This suggests that the macroions dehydrate the activated complex more strongly than the reactants, if it may be attributed solely to the solute-solvent interaction term.
