Two points on a diatomic molecule’s potential-energy curve are labeled: point A at

0.11\,\text{nm}

with potential energy

-320\,\text{kJ}\cdot\text{mol}^{-1}

and point B at

0.15\,\text{nm}

with potential energy

-240\,\text{kJ}\cdot\text{mol}^{-1}

. Which point is closer to the equilibrium bond length? Explain your reasoning in one sentence.
