chemical engineering thermodynamics

A piston-cylinder assembly initially contains 0.1m3 of ethylene gas at 393K and 35 bar pressure. The pressure of the gas in the pistoncylinder assembly is reversible and isothermally brought to 205 bar (In all cases below, the conditions for this compression process will be used). a) Assuming that ethylene obeys the ideal gas equation, the heat transferred between the system and its surroundings Calculate (J/mol) and work done (J/mol). b) Assuming that ethylene obeys the Peng-Robinson equation of state, the internal energy during the process Calculate the change (J/mol).
