Calculation of the Fugacity of a Gas Using the Virial Equation
Compute the fugacities of pure ethane and pure butane at 373.15 K and 1, 10, and 15 bar, assuming the virial equation of state can describe these gases at these conditions.
Data:
\begin{aligned}&B_{\mathrm{ET}}(373.15 \mathrm{~K})=-1.15 \times 10^{-4} \mathrm{~m}^{3} / \mathrm{mol} \\\\&B_{\mathrm{BU}}(373.15 \mathrm{~K})=-4.22 \times 10^{-4} \mathrm{~m}^{3} / \mathrm{mol}\end{aligned}
