Kinetics of aquation of the hexabromorhenate(IV) and hexachlororhenate(IV) ions
Abstract
The kinetics of aquation of the hexabromorhenate(IV) ion in aqueous solution and aqueous organic media, and those of the hexachlororhenate(IV) ion in aqueous solution in the presence of mercury(II) ions, are reported. Activation parameters for the aquation of the hexabromorhenate(IV) ion in aqueous solution are ΔH‡= 26·0 kcal mol–1 and ΔS‡=–6 cal K–1 mol–1.
