Calculate kB T for T = 500 K in the following units: erg, eV, cm¹, wave length, degrees Kelvin, and Hertz. The vibrational energy of a diatomic molecule is E, = ħw (v + 1/2), v= 0, 1, 2, .... For H₂, ħ w = 4401 cm¹. For 1₂, ħw=214.52 cm¹. Without performing a calculation tell which molecule has higher vibrational entropy. Explain your reasoning. Use ListPlot to make a plot of the probability that an 1₂ molecule has the vibra tional energy Ev, for v = 1,2,3,4,5,6. Calculate the vibrational entropy of /2 by using the formula giving entropy in terms of probabilities. Plot the vibrational entropy versus temperature in the range T€[298, 700] degrees Kelvin. * Calculate the vibrational entropy of /2 by calculating the vibrational partition function, the vibrational Helmholtz free energy A(T), and then S(T) = a A(T)/OT (keep N constant). Plot S(T) in the range T€[298, 700] degrees Kelvin. Should you get the same result as in Problem 4? Does the vibrational motion affect the pressure of an ideal gas? Calculate the mean vibrational energy U(T) = Thermodynamics tells us that A(T) = U(T)  T S(T). Verify that this is true. Ev P(Ev) of 1₂ for T = 600K.
