The vapor pressure of a single component, 2 phase system (vapor is assumed to be ideal gas) was measured using a sealed-end manometer at different temperatures. Given the following data: Temperature (K) 251.2 286 321.5 345 Pressure (mmHg) 36 304 815 1021 Solve the following: a. What does the enthalpy change of vaporization in kJ/mol? b. What is the normal boiling point @ T=321.5 K? c. Is the chemical species of interest vapor, liquid, or both at room temperature? Why?
