- Using the Peng-Robinson equation of state, plot the P-V isotherm for carbon dioxide at 275K for specific volumes up to 500cm3/mol - Also show the horizontal line that connects the vapor and liquid specific volumes at the saturation pressure. For drawing this line, estimate Psat using the shortcut vapor pressure equation log10Prsat37(+1)(1Tr1) (The shortcut vapor pressure equation must be regarded as an approximation for rapid estimates. The approximation is generally good above Tr=0.5. Use care with the shortcut equation below Tr=0.5. When the vapor pressure is below approximately 2 bar, the percent error with the shortcut prediction can become large). - Does Maxwell's equal area rule seem to apply to this isotherm
