(15 pts) (a) Start with equations 17.43 and 17.54 of the David Ball textbook and show that the absolute entropy of a monatomic ideal gas is h2 (b) Treat Ar as a monatomic ideal gas and calculate the absolute entropy of 1.00 mole of argon gas at 298 K and a pressure of 1.00 atm based on the equation above. Compare your calculated value to the calculated and experimental values given for Ar in Table 17.1 of the textbook.(15 pts) The first four energy levels of the neon atom have energies of 0.0, 134041.84, 134459.29, and 134818.64 cm1 with degeneracies of 1, 5, 3, and 1 respectively (see https://physics.nist.gov/PhysRefData/Handbook/Tables/neontable5.htm). (a) Convert these energies into Joules and create a table similar to that given for the carbon atom in Example 18.1 of the David Ball textbook. (b) Calculate the first four terms in the sum of qelect for neon at 298 K. (Note: you will probably need to use Microsoft Excel for these calculations, as some of the numbers that you will get are so tiny that a calculator will give you an error message.) (c) What is the overall value of Gelect for neon at 298 K? (d) Calculate Qtrans for 2.00 mol of neon at 298 K, assuming it is an ideal gas in a volume of 30.00 L. Explicitly show how the units cancel out properly to make qtrans a unitless number. (e) Calculate the internal energy (E) of 2.00 mol of neon at 298 K, assuming it is an ideal gas in a volume of 30.00 L
