In a qualitative potential-energy curve for a diatomic molecule, which location on the curve corresponds to the equilibrium bond length, re?
(a) The internuclear distance at which the curve first begins to drop below zero potential energy.
(b) The internuclear distance at which the potential-energy curve changes concavity (point of inflection).
(c) The internuclear distance at which the potential energy reaches its minimum value.
(d) The internuclear distance on the right side of the graph where the potential energy returns to zero.
