**P5.38**: Consider the reversible Carnot cycle shown in Figure 5.13 with 1.25 mol of an ideal gas with \( C_V = \frac{5R}{2} \) as the working substance. The initial isothermal expansion occurs at the hot reservoir temperature of \( T_{\text{hot}} = 825 \, \text{K} \) from an initial volume of 2.25 L (\( V_a \)) to a volume of 10.5 L (\( V_b \)). The system then undergoes an adiabatic expansion until the temperature falls to \( T_{\text{cold}} = 298 \, \text{K} \). The system then undergoes an isothermal compression and a subsequent adiabatic compression until the initial state described by \( T_a = 825 \, \text{K} \) and \( V_a = 2.25 \, \text{L} \) is reached.
