Question

a) Use the virial equation of state to estimate the fugacity of methane at 600 K and 1, 5, 10, 50, and 100 bar.

Do the same estimation for methanol at 600 K and 100 bar.

Plot f/P for both gases on the same axes.

Comment on what you learn from this comparison.

b) Repeat the analysis of part a at the same T and P using the Peng Robinson equation of state.

Predict what would happen if you redid the analyses for H2 and for dodecane.
