QUESTION 3 For cyclohexane at State 1 (T-127 °C and P-12 bar) that is cooled to its saturated vapor in State 2 at T-59 °C: a. Find the change in enthalpy for cyclohexane going from State 1 to State 2 as predicted by the Peng-Robinson equation (Note. printouts for Peng Robinson are given in your exam folder.) Briefly explain your choice of excel sheets you used! b. What is the value for the molar volume of cyclohexane at State 27 Show how you can use the Z. P. and T values from the excel spreadsheet to calculate the molar volume at State 2. c. For State 2, estimate the vapor pressure using the appropriate saturation pressure calculation. Briefly explain your choice of saturation pressure equation. d. At State 1 would the deviations of the fluid from the ideal gas law be considered to be large or small? (Give a brief explanation for your answer and provide values from the excel sheet that support your answer.)
