question 10

Multiple Choice

Estimate the rotational energy (in eV) for a diatomic hydrogen molecule in the l = 2 quantum state. (The equilibrium separation for the H₂ molecule is 0.074 nm.) (1 eV = 1.60 × 10^-19 J, h = 6.626 × 10^-34 J ∙ s, = 1.055 × 10^-34 J ∙ s, ^mH ≈ ^mproton = 1.67 × 10^-27 kg)

• A) 0.011 eV
• B) 0.026 eV
• C) 0.032 eV
• D) 0.046 eV
• E) 0.055 eV
