N2  - The aquation of Fe(bpy)32+ (bpy = 2,2'-bipyridyl) was studied in aqueous hydrochloric acid at a range of pressures between 1 and 2070 bar. Activation volumes (&#916;V&#8225;) in 1.0 M HCl (+ 12.3 cm3 mol-1), 0.01 M HCl (+14.8cm3 mol-1), 1.0 M DCl (+13.3 cm3 mol-1) and 0.01 M DCl (+16.3 cm3 mol-1) were determined. A mechanism involving a significant positive contribution to &#916;V&#8225; arising from a low-spin &#8596; high-spin preequilibrium is proposed. The minor effect of the deuterium solvent isotope on &#916;V&#8225; is consistent with this proposal.
