This problem concerns a compound for which the following information is available:
• The triple point is located at P=0.8 atm and T=300 K.
• The critical point is located at P=40 atm and T=650 K.
• The acentric factor is 0.25.
• At P=1 atm, boils at 314 K.
• At P=1 atm, the molar volume is 0.12 L/mol for solid and 0.132 L/mol for liquid.
• At the triple point, the enthalpy of fusion/melting is 5000 J/mol.
Give your best estimate of each of the following:
A) The enthalpy of vaporization at the triple point.
B) The vapor pressure at 305 K.
C) The vapor pressure at 500 K.
D) The pressure at which the compound has a melting temperature of 301 K.
