Abstract
The kinetics of the reactions involved in the formation of the mono–fluoro complex of iron (III) in aqueous solutions have been examined spectrophotometrically at ionic strength 0.5 and over the temperature interval 0.1 to 12.1 °C. The results are interpretable on the assumption that the following two reactions contribute significantly to the rate Fe+++ + F− = FeF++ and Fe+++ + HF = FeF++ + H+, the former having a heat of activation of 22.8 ± 2.5 kcal mole−1 and an entropy of activation of 35 ± 9 cal deg−1 mole−1, the latter having a heat of activation of 8.7 ± 0.7 kcal mole−1 and an entropy of activation of −24.5 ± 3 cal deg−1 mole−1.Keywords
