One mole of an ideal gas (CP/R=7/2), is compressed in a steady-flow compressor from 2.5 bar and 25°C to 6.5 bar and 120°C. The compressor rejects 0.5 kJ as heat to the surrounding at 293K.

Calculate:

1.     The enthalpy change of the gas (in kJ)

2.     The entropy change of the gas (in J.mol-1)

3.     The work required for the compression (in kJ)

4.     The ideal work of the process (in kJ)

5.     The thermodynamic efficiency

The lost work (in kJ)
