That problem asked you to estimate the change in molar enthalpy when hydrogen is compressed from T = 300 K and P = 1 bar to T = 700 K and P = 200 bar. At that time, the ideal gas model was the only method we had available to solve the problem. Now use the Peng-Robinson equation of state to solve this problem.

A. Find the change in molar enthalpy when hydrogen is compressed from T = 300 K and P = 1 bar to T = 700 K and P = 200 bar.

B. Find the work required to compress each mole of hydrogen from T = 300 K and P = 1 bar to T = 600 K and P = 10 bar in an adiabatic, steady-state compressor.

C. Find the heat removed from each mole of hydrogen if the gas leaving the compressor in part B is cooled to T = 300 K and P = 10 bar in a steadystate heat exchanger.

D. Find the work required to compress each mole of hydrogen from T = 300 K and P = 10 bar to T = 800 K and P = 200 bar in an adiabetic, steady-state compressor.

E. For each of the compressors in parts B and D, comment on whether their operation is physically realistic as described, and show calculations that support your conclusions.
