1.) A reversible cycle executed by 1 mol of an ideal gas for which Cp = (5/2)R and Cv = (3/2)R consists of the following: • Starting at T1 = 700K and P1 = 1.5 bar, the gas is cooled at constant pressure to T2 = 350K • From 350K 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?
