The Delta(eg)H^(ɵ) of Br is 3.4 eV. How ...

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)`.
