The vapor pressure of benzene at T=25 °C is 0.125 bar. The Appendix of your book contains enough additional data on benzene to estimate other vapor pressures by the Antoine, shortcut, or Clausius-Clapeyron approaches.
The molar volume of liquid benzene at room temperature and pressure (T=25 °C, P=1 bar) is V = 88.9 cm3/mol. Liquid benzene also has a coefficient of thermal expansion of ? =1.237 x 10-3 K-1and isothermal compressibility of ? = 8.9 x 10-5bar-1 A) Give your best estimate of the vapor pressure of benzene at T=50 °C, and explain why you chose the method that you chose. B) Give your best estimate of the vapor pressure of benzene at T=100 °C, and explain why you chose the method that you chose. C) Give your best estimate of the fugacity of liquid benzene at T=25 °C and P=20 bar, and state any assumptions that you make. D) (10 points) Benzene expands as it’s heated. Estimate the molar volume of liquid benzene at a temperature of 50 °C and a pressure of P=1 bar.
