The `Delta_(eg)H^(ɵ)` of `Br` is `3.4 eV`. How much energy in kcal is released when `0.8 g` of `Br (g)` is completely converted to `Br^(ɵ) (g)` ions. `(1 eV = 23.06 kcal mol^(1-))`
b. The energy released when `10^(7)` atoms of `I (g)` is converted to `I^(ɵ) (g)` ions, is `5 xx 10^(-13) J`. Calculate `Delta_(eg)H^(ɵ)` of `I (g)` in (i) `eV "atom"^(-1)` and (ii) `kJ mol^(-1)`.

Explanation

To solve the problem step by step, we will break it down into two parts as given in the question.

### Part (a): Energy released when 0.8 g of Br(g) is converted to Br⁻(g) ions

1. **Determine the molecular weight of Br₂**:
- The atomic weight of bromine (Br) is approximately 80 g/mol.
- Therefore, the molecular weight of bromine gas (Br₂) is:
\[
