Problem- Ammonia is to be isothermally compressed in a specifically designed flow turbine from 1 bar and 100oC to 50 bars. If the compression is done reversibly, compute the heat and work flows needed per mole of ammonia if it obeys the peng-robinson equation of state.
I want you to explain the chemistry in this problem
