The figure below is the plot of potential energy versus internuclear distance (d) of \( \mathrm{H}_{2} \) molecule in the electronic ground state. What is the value of the net potential energy \( \mathrm{E}_{0} \) (as indicated in the figure) in \( \mathrm{kJ} \mathrm{mol}^{-1} \), for \( \mathrm{d}=\mathrm{d}_{0} \) at which the electronelectron repulsion and the nucleus-nucleus repulsion energies are absent? As reference, the potential energy of \( \mathrm{H} \) atom is taken as zero when its electron and the nucleus are infinitely far apart.
