Problem

Determine the ionisation energy per mole for the

\text{He}^+

ion. (Given:

1\,\text{eV}=1.6\times10^{-19}\,\text{J}

N_A = 6.02\times10^{23}\,\text{mol}^{-1}

.) a)

2.6\times10^{3}\,\text{kJ\,mol}^{-1}

1.0\times10^{4}\,\text{kJ\,mol}^{-1}

5.2\times10^{3}\,\text{kJ\,mol}^{-1}

1.3\times10^{3}\,\text{kJ\,mol}^{-1}
