Two potential-energy curves for diatomic molecules are described below.
• Curve A reaches its minimum potential energy at −120 kJ·mol⁻¹ and an internuclear distance of 0.110 nm.
• Curve B reaches its minimum potential energy at −410 kJ·mol⁻¹ and an internuclear distance of 0.090 nm.
Which curve corresponds to a molecule with a triple bond? Briefly explain your reasoning in one sentence.
