with the aid of the standard expressions for the translational, rotationl and vibrational partition functions q for a diatomic molecule,obtain the respective contributions to the total internal energy per mole, U-U(0) = NAkbT2 (δ lnq/δT)v and hence to the total capacity Cv for 1 mole of iodine gas t 50 and 400K . For I2, the rotational temperature θR=0.0538 k and the vibrational temperature θv = 308.65 K. would the vibrational contributions to U-U(0) and Cv still be significant at 100K? please explain.
