An inventor has devised a complicated non flow process in which 1 mol of air is the working fluid. The net effects of the process are claimed to be:

A change in state of the air from 523.15 K (250°C) and 3 bar to 353.15 K (80°C) and 1 bar.

The production of 1800 J of work

The transfer of an undisclosed amount of heat to a heat reservoir at 303.15 K (30°C)

Determine whether the claimed performance of the process is consistent with the second law. Assume that air is an ideal gas for which C_p = (7/2)R.
