The electron gain enthalpy of chlorine 3...

The electron gain enthalpy of chlorine `3.7 eV`. How much energy in `kJ` and `kcal` is released when `1 g` of chlorine is converted completely to `Cl^(o-)` ion in the gaseous state. `(1 eV = 96.3 kJ mol^(-1))`

Text Solution

Verified by Experts

The correct Answer is:
1
Energy released for the conversion of 2.0 g of gaseous chlorine to chloride ion `=(3.7 xx 23.06 xx 2)/(35.5)=4.9kcal`
