Chapter 6: Q 6.28 (page 237)
Use a computer to sum the rotational partition function (equation 6.30) algebraically, keeping terms through j = 6. Then calculate the average energy and the heat capacity. Plot the heat capacity for values of ranging from 0 to 3. Have you kept enough terms in Z to give accurate results within this temperature range?
Short Answer
The average energy is and
The average heat capacity is
