a. At 1.50 atm and 100.0C, what is vapor pressure of 1-octanol in mm Hg?

b. Assuming Raoult's law is valid, what is the K value of 1-octanol at 1.50 atm and 100.0C?

c. An alternate source for Antoine constants gives A = 6.8379, B = 1310.62, C136.05 with T in C and vapor pressure in mm Hg. Compare answers using this data to the results using NIST data in parts a and b.

d. Compare the predictions for vapor pressure in mm Hg of 1- propanol (n-propanol) at 25.3 and 75C using the Antoine coefficients in Table 2-3 with the tabulated values in Problem 6.D4.

Data From D4

A mixture of methanol and water is sent to a flash distillation drum operating at 1.0 atm. Feed rate is 10.0 kmol/h. The feed before the valve in Figure 2-1 is at 102.0C and a pressure of 5.0 bar. Equilibrium data are in Table 2-8.
