Calculate the n-factor of reactants in the given reactions.
(d) `Fe(NO_(3))_(3)rarr Fe^(2+)+NO`

Explanation

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

\[ \text{Fe(NO}_3\text{)}_3 \rightarrow \text{Fe}^{2+} + \text{NO} \]

we will follow these steps:

### Step 1: Determine the oxidation state of iron in Fe(NO3)3
In the compound Fe(NO3)3, we need to find the oxidation state of iron (Fe). The nitrate ion (NO3) has a charge of -1, and since there are three nitrate ions, the total negative charge contributed by the nitrate ions is -3.
