Determine the enthalpy of vaporizaton of species:
You wish to determine the enthalpy of vaporizaton of species A. You are able to find the following data: Species A has a normal boiling point of 207.3 K and at 20.0 atm, it boils at 301.5 K. The following equation of state is reported:
with a = 25 K. As best as you can estimate ?vaph . State any assumptions that you make.
You need to find the enthalpy of sublimation of solid A at 300 K. The following equilibrium vapor pressure measurements have been made on pure A: (1) at 250 K, the pressure is 0.258 bar and (2) at 350 K, the pressure is 2.00 bar. The following heat capacity data are known:
A. Calculate the enthalpy of sublimation, assuming ?hsub is constant.
B. Calculate the enthalpy of sublimation, accounting for the temperature variation of ?hsub .
C. Estimate the error in the constant T assumption.
