Calculate the energy in fusion reaction .
`overset(2)underset(1).H +overset(2)underset(1).H` `to overset(4)underset(2).He + n` " where BE of " `overset(2)underset(1).H=2.23 MeV`" and of " `overset(4)underset(2).He =7.73 MeV`

Explanation

To calculate the energy released in the fusion reaction \( \overset{2}{1}\text{H} + \overset{2}{1}\text{H} \rightarrow \overset{4}{2}\text{He} + n \), we will use the concept of binding energy.

### Step-by-Step Solution:

1. **Identify the Binding Energies**:
- The binding energy (BE) of deuterium (\( \overset{2}{1}\text{H} \)) is given as \( 2.23 \, \text{MeV} \).
- The binding energy of helium (\( \overset{4}{2}\text{He} \)) is given as \( 7.73 \, \text{MeV} \).
