Calculate the n-factor of reactants in the given reactions.
(c ) `[Fe(CN)_(6)]^(4-)rarr Fe^(3+)+CO_(2)+NO_(3)^(-)`

Explanation

To calculate the n-factor of the reactants in the reaction:

\[ [Fe(CN)_{6}]^{4-} \rightarrow Fe^{3+} + CO_{2} + NO_{3}^{-} \]

we will follow these steps:

### Step 1: Determine the oxidation state of iron in the reactant
In the complex ion \([Fe(CN)_{6}]^{4-}\), we need to find the oxidation state of iron (Fe).
