Please help me with part b, also I got q=-13.90kJ/mol and w=11.42kJ/mol on part a but not sure if its correct please correct me if Im wrong

Question 1 [30] Ammonia is to be isothermally compressed in a specially designed flow turbine from 1 bar and 100C to 50 bar. If the compression is done reversibly, compute the heat and workflow needed per mole of ammonia if: a. Ammonia obeys the principle of corresponding states (Equations 89-90 of Chapter 5). [15] b. Ammonia obeys the Peng-Robinson equation of state. Use an appropriate MATHCAD code. Insert a PDF output of the code in your solution. Make sure to include your name and student number in the code.
