Question
Transcribed Image Text:2. The vapor pressure of tetrachloromethane (tcm) and trichloroethylene (tce) can be
expressed as the following functions of T (°C) in the range between the boiling point of
pure tem (76.7°C) and tce (87.2°C):
2790.78
In(Picm/torr) × 15.8401
T + 226.4
2345.4
In(Pice/torr) 15.0124 –
T + 192.7
Use the information to answer the following questions about a tcm+tce mixture.
a. Make a graph of T vs. Xtce and Yice (similar to Figure 24.5) and use this graph to calculate the
answers to questions b-d. (Hint: see Example 24-5 on page 975 and lecture slides)
b. What is the normal boiling point of the mix when the mole fraction of tce is 0.6 (xtce = 0.6)?
c. At the boiling point calculated in (b), what are the mole fractions of tcm and tce
(Ytcm and ytce) in the vapor?
d. What is the normal boiling point of the condensate of the vapor in (c)?
