2 ± 0.5 kcal mol–1 and ΔS‡=–13.5 ± 1.7 cal K–1 mol–1. Aquation of [Cr(NH3)5F]2+ yields [Cr(NH3)5(H2O)]3+(k2) and [Cr(NH3)4(H2O)F]2+(k3) with the latter predominating over the conditions [H+]= 0.01–1.00M investigated. From product analyses and kinetic studies at different [H+] rate constants have been obtained at 50 °C. I = 1.00M(LiClO4). Aquation of fluoride is [H+]-dependent,k2=a+b[H+] with a= 2.1
