Practice Exercise VLE Modified Raoult's Law
Iteration and solution in math lab
(d) A DEW T calculation.
P = 101.33 kPa,
Saturation T same in part (c), use Ave T as
initial value for T = 333.895 K
Because the liquid-phase composition is not known, the activity
coefficients are initialized as γ1 = γ2 = 1.
Trial calculations alternately vary T to reproduce the given
value of P and then x1 to reproduce the known value of y1. The
process yields the following final values
