5.34 One mole of CO is initially contained on one-half of a well-insulated, rigid tank. Its tem- perature is 500 K. The other half of the tank is initially at vacuum. A diaphragm separates the two compartments. Each compartment has a volume of 1 L. Suddenly, the diaphragm ruptures. Use the van der Waals equation for any nonideal behavior.
(a) What is cv at the initial state?
(b) Do you expect the temperature to increase, decrease, or remain constant. Justify your answer with molecular arguments. Be specific about the nature of the forces involved.
(c) What is the temperature of the final state?
(d) What is the entropy change of the universe for this process?
