Verified by Experts

The amount of energy released when `1 xx 10^(10)` atoms of chlorine in vapour state are converted to `Cl^(-)` ions, according to the equation,
`Cl_(g) +e^(-) to Cl_(g)^(-)` is `57.86 xx 10^(-10)` J
`:.` The electron gain enthalpy of chlorine, i.e., the amount of energy released when 1 mole (`6.023 xx 10^(23)` ) atoms of chlorine are converted into `Cl^(-)` ions according to the above equation will be
`= -(57.86 xx 10^(-10))/(1xx 10^(10)) xx 6.023 xx 10^(23)`
`= -348.49 xx 10^(3) J//mol= -348. 49 kJ//mol`
Now 1 eV/ atom=` 96.49 kj mol^(-1)`
`:.` Electron gain enthalpy of chlorine =` (348.49)/(96.49)= -3.61 eV//"atom"`
