The rate of formation of the complex

[Fe(dipy)_3]^{2+}

at 25°C following the reaction:

Fe^{2+} + 3 dipy \rightleftharpoons [Fe(dipy)_3]^{2+}

is given as :

rate = 1.45 \times 10^{13} [Fe^{2+}] [dipy]^3

The rate of disappearance of complex is given as :

rate = 1.22 \times 10^{-4} [Fe(dipy)_3]^{2+}

Calculate the stability constant of complex. *dipy* is abbreviated for dipyridyl a chelating agent.
