Two pounds of carbon dioxide (CO_{2}) as an ideal gas executes a Carnot power cycle while operating between thermal reservoirs at 530 and 100^{o}F. The pressures at the initial and final states of the isothermal expansion are 400 and 200 lb_{f}/in^{2}, respectively. The specific heat ratio is *k* = 1.24.

Determine the thermal efficiency, the work for the isothermal expansion, in Btu, and the work for the adiabatic expansion, in Btu.
