The complexation of `Fe^(2+)` with the chelating agent dipyridyl has been studied kinetically in both forward and reverse directions .
`Fe^(2+) +3 dipy to Fe ("dipy")_(3)^(2+)`
Rate (forward) = `(1.45 xx10^(13)) [Fe^(2+)] ["dipy"]^(3)`
and rate (reverse) = `(1.22 xx10^(-4)) [Fe ("dipy")_(3)^(2+)]`
Find the stability constant for the complex .

Explanation

To find the stability constant for the complexation of `Fe^(2+)` with the chelating agent dipyridyl, we can follow these steps:

### Step 1: Write the reaction and identify the rates
The reaction can be written as:
\[ \text{Fe}^{2+} + 3 \text{dipy} \rightleftharpoons \text{Fe(dipy)}_3^{2+} \]

The rates for the forward and reverse reactions are given as:
- Rate (forward) = \( 1.45 \times 10^{13} [\text{Fe}^{2+}] [\text{dipy}]^3 \)
