Energy of 10 non rigid diatomic molecules at temperature T is: (a) 35 RT (b) 7/2 RT (c) 70 KBT (d) 35 KBT

Answer: (d). Non-rigid diatomic: f = 3 + 2 + 2 = 7 (vibration gives 2 terms). Energy per molecule = 7/2kBT; for 10 molecules E = 10 × 7/2kBT. So the answer is (d) 35kBT.

Degrees of Freedom & Internal Energy

Energy of 10 non rigid diatomic molecules at temperature $T$ is:

Show answer and solution

Answer: (d)

Non-rigid diatomic: $f = 3 + 2 + 2 = 7$ (vibration gives 2 terms).
Energy per molecule $= \frac{7}{2}k_BT$ ; for 10 molecules $E = 10 \times \frac{7}{2}k_BT$ .
So the answer is (d) $35k_BT$ .
