Unformatted text preview: a = 1.36 ⋅ atm ⋅ mole –2 and b = 0.0318 ⋅ mole –1 , calculate the work, heat, internal energy change, enthalpy change, entropy change, and free energy change when one mole of oxygen gas is expanded from 1 to 2 at 300 K. Do the same calculations assuming that oxygen behaves as an ideal gas and compare your values. (12 points) e) Now consider that you would like to purchase oxygen for use in your lab. The oxygen gas will be stored at a pressure of 250 atm at room temperature in a cylinder that is 2 m high with a diameter of 0.25 m. If the vendor charges a price that is per liter of gas, would you prefer that the gas behaved ideally or as a van der Waals gas? (5 points)...
