Aquation of tris(5-nitro-1,10-phenanthroline) iron(II) in binary aqueous mixtures; comparison of kinetic parameters for reaction and thermodynamic properties of the mixtures

Abstract

Rate constants for the aquation of tris(5-nitro-1,10-phenanthroline)iron(II) have been determined in a wide range of binary aqueous mixtures. The results are presented and discussed in terms of correlation diagrams involving the excess molar Gibbs function of mixing for the binary mixtures. The behaviour of this iron(II) complex is compared and contrasted with that of t-butyl chloride. The possible advantages of this mode of treatment of kinetic results are outlined.
