Question
The complexion of Fe2+ with the chelating agent dipyridyl has been studied kinetically in both the forward and reverse directions. Fe2+ + 3 dipy$\rightleftharpoons$ [Fe (dipy)3]2+
For this reaction, the rates of forward and reverse reactions are
(1.45 × 1013 M−3 s−1)[Fe2+][dipy]3 and (1.22 × 10−4 s−1) [Fe (dipy)32+], at 25oC.
What is the stability constant of the complex?
Options
A.1.77 × 109
B.8.4 × 10–18
C.1.18 × 1017
D.5.65 × 10–10
Solution
Stability constant, $K = \frac{K_{f}}{K_{b}} = \frac{1.45 \times 10^{13}}{1.22 \times 10^{- 9}} = 1.1885 \times 10^{17}$
