## Question:

Use the SRK equation to obtain the saturation pressure of propane at 350 K. Perform the calculation as follows:

a) Determine the highest pressure at which the vapor phase is stable (P1).

b) Determine the lowest pressure at which the liquid is stable (P2).

c) Plot the fugacity coefficient of the vapor starting from a pressure close to the ideal-gas state up to the highest pressure where the vapor is stable. On the same graph make a plot of the fugacity coefficient of the liquid starting from the lowest pressure where the liquid is stable up to some pressure into the compressed-liquid region.

d) Identify the saturation pressure as the pressure where the liquid and vapor fugacity lines cross. How does this result compare with the literature value for the saturation pressure of pentane at 350 K?
