Calculate the n-factor of reactants in the given reactions.
(e ) `Fe_(2)(SO_(4))_(3)rarr Fe^(2+)+SO_(2)`

Explanation

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

\[ \text{Fe}_2(\text{SO}_4)_3 \rightarrow \text{Fe}^{2+} + \text{SO}_2 \]

we will follow these steps:

### Step 1: Determine the oxidation state of iron in the reactant.
In the compound \(\text{Fe}_2(\text{SO}_4)_3\):
...
