5.34Â Â Â 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)Â Â Â Â What is cv at the initial state?
(b)Â Â Â Â 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)Â Â Â Â What is the temperature of the final state?
(d)Â Â Â What is the entropy change of the universe for this process?
