`K_(1),K_(2)`and `k_(3)` for the complexation of `SCN^(Θ)` with `Fe^(3+)` are `130, 16,` and `1.0`, respectively. (i) Calculate the overall formation costant of `Fe(SCN)_(3)` from its constituent ions.

Explanation

To calculate the overall formation constant \( K \) for the complexation of \( \text{Fe}^{3+} \) with \( \text{SCN}^- \) to form \( \text{Fe(SCN)}_3 \), we can follow these steps:

### Step 1: Write the individual complexation reactions
1. The first reaction is:
\[ \text{Fe}^{3+} + \text{SCN}^- \rightleftharpoons \text{Fe(SCN)}^2+ \quad K_1 = 130 \]
