For cyclohexane at = 400 K and P = 1 MPa, use the Peng-Robinson EOS to find the liquid and vapor phase fugacities, and determine which phase is stable at equilibrium.
A. fL = 0.312 MPa, fV = 0.817 MPa, vapor phase stable
B. fL = 0.312 MPa, fV = 0.817 MPa, liquid phase stable
C. fL = 0.312 MPa, fV = 0.768 MPa, vapor phase stable
D. fL = 0.312 MPa, fV = 0.768 MPa, liquid phase stable
E. None of these are correct.
A. Incorrect. You picked the wrong roots of the EOS to calculate the fugacity from and interpreted the fugacities incorrectly.
B. Incorrect. You picked the wrong roots of the EOS to calculate the fugacity from.
C. Incorrect. You interpreted the fugacities incorrectly.
D. Correct. The lower fugacity represents the stable phase.
E. Incorrect. One of these options is correct.
