Using the Van Laar model and the data from problem 11.3, estimate the total pressure and composition of the vapor in equilibrium with a 20 mol% ethanol(1) solution in water(2) at 78.15oC. Note: The information from problem 11.3 is as follows: T = 78.15oC P1sat = 1.006 bar P2sat = 0.439 bar γ1∞ = 1.6931; γ2∞ = 1.9523

Question:

Using the Van Laar model and the data from problem 11.3, estimate the total pressure and composition of the vapor in equilibrium with a 20 mol% ethanol(1) solution in water(2) at 78.15oC.

Note: The information from problem 11.3 is as follows:

T = 78.15oC

P1sat = 1.006 bar

P2sat = 0.439 bar

γ1∞ = 1.6931; γ2∞ = 1.9523

Request:
