- At temperature T, the internal energy of 1mol rigid diatomic molecules is =......Calculate the value of Cp at 298K and 1 atm pressure predicted for CH4(g) and C2H4(g) by the classical equipartition theorem. Compare the predicted results with the experimental results (see OGB Appendix D) and calculate the percent of the measured value that arises from vibrational degrees of freedom.Indicate whether each statement is true or false. (a) Unlikeenthalpy, where we can only ever know changes in H, wecan know absolute values of S. (b) If you heat a gas suchas CO2, you will increase its degrees of translational, rotationaland vibrational motions. (c) CO2(g) and Ar(g) havenearly the same molar mass. At a given temperature, theywill have the same number of microstates.
- Calculate the vibrational, rotational, and translational contributions to the constant volume heat capacity (Cv) for 14N2 at 298 K. Assume this represents the high temperature limit for rotational energy and low temperature limit for vibrational energy. Given that Cv=20.81 J/K·mol for N2, state which type or types of energy contribute most to Cv for N2 and explain why those types of energy contribute most.3. At T = 300K, 1bar of ¹60¹80 in a 1m³ box (lengths ax ay = az = 1m) can be considered as an ideal gas. In that case, the average translational energy in each dimension for a molecule is given by: Ex = Ex = Ex = 1kT, where k = 1.38 x 10-23 J/K is the Boltzmann constant. The average rotational energy about an axis perpendicular to the O=O bond is: Erot=kT, Evib = KT. and the average vibrational energy is: Given that the fundamental vibrational frequency for ¹60¹80 is w = 4.741 x 10¹³ Hz, find the values of the quantum numbers nx, J, and u for an average ¹60¹80 molecule in this system.The force constant for HF is 966 N m-1. Using the harmonic oscillator model, calculate the relative population of the first excited state and the ground state at 300 K.

The ground electronic state has a degeneracy of 4.Q 1. Use the equipartition principle to estimate the value of γ = Cpm/CVm for gaseous CH3COOH. Do this calculation WITH the vibrational contribution to the energy.
