Calculate the n-factor of reactants in the given chemical changes
(e ) `As_(2)O_(3)rarrAs_(2)O_(5)`

Explanation

To calculate the n-factor of the reactant \( \text{As}_2\text{O}_3 \) in the reaction \( \text{As}_2\text{O}_3 \rightarrow \text{As}_2\text{O}_5 \), we will follow these steps:

### Step 1: Determine the oxidation states of arsenic in both reactant and product.

1. **For \( \text{As}_2\text{O}_3 \)**:
- Let the oxidation state of arsenic (As) be \( x \).
- The oxidation state of oxygen (O) is -2.
- The equation for the compound is:
