Prepare plots of f vs. P and phi vs. P for isobutane at 40 degC. Use a pressure range 0 to 10 bar. At 40 degC, the vapor pressure of isobutane is 5.28 bar.
Use the SRK EOS to determine the fugacity coefficient of saturated vapor/liquid isobutane. You can also use SRK to calculate the fugacity coefficient of superheated vapors directly. Then, it is relatively easy to calculate the fugacity of the superheated vapors. Subcooled liquids require the use of SRK and the Poynting Factor. Then, use the SRK EOS to estimate the molar volume of saturated liquid isobutane.
Plot 21 data points from 0 to 10 bar, every 0.5 bar. This will entail using Solver for each data point. Remember to completely label your plots.

On graphing the Fugacity and the Fugacity coefficient, should we just make two different graphs with a different axis or should we make one with the double axis, like in class. For curiosity I was wondering how you can make a duel axis, one on the right and one on the left.

You can go either way, two graphs or one. To use a secondary y-axis, make the plot with both series on one graph. It will not look very good. Right-click on one of the series and select "Format Data Series" from the drop-down menu. Choose the "Axis" tab. On this tab, select the "Plot series on secondary axis" radio button and click OK. Viola, you have a secondary axis.
