Calculate the n-factor of reactants in the given reactions.
(b) `FeC_(2)O_(4)rarr Fe^(3+)+CO_(2)`

Explanation

To calculate the n-factor of the reactant in the reaction \( \text{FeC}_2\text{O}_4 \rightarrow \text{Fe}^{3+} + \text{CO}_2 \), we will follow these steps:

### Step 1: Identify the oxidation states of the elements in the reactant.
In the compound \( \text{FeC}_2\text{O}_4 \):
- The oxidation state of iron (Fe) is +2.
- The oxidation state of carbon (C) in \( \text{C}_2\text{O}_4^{2-} \) can be calculated as follows:
Let the oxidation state of carbon be \( x \).
The equation for the oxidation state is:
