A reversible cycle executed by 1 mol of an ideal gas for which Cp = (5/2)R and Cy= (3/2)R consists of the following: Starting at T₁ = 700 K and P₁ = 1.5 bar, the gas is cooled at constant pressure to T₂ = 350 K. From 350 K and 1.5 bar, the gas is compressed isothermally to pressure P2. The gas returns to its initial state along a path for which PT = constant.

Question
5.25. A reversible cycle executed by 1 mol of an ideal gas for which Cp = (5/2)R and Cy= (3/2)R consists of the following: Starting at T₁ = 700 K and P₁ = 1.5 bar, the gas is cooled at constant pressure to T₂ = 350 K. From 350 K and 1.5 bar, the gas is compressed isothermally to pressure P2. The gas returns to its initial state along a path for which PT = constant. What is the thermal efficiency of the cycle?
