HW 3 - p 4.35 - Bubble Pt, Dew Pt and Azeotrope of Ethanol-Ethyl Acetate Mixtures - 7 pts
(a) For a liquid solution having a molar composition of ethyl acetate (A) of 80% and ethyl alcohol (E) of 20%, calculate the bubble-point temperature at 101.3 kPa and the composition of the corresponding vapor using (2-27) with vapor pressure data and the van Laar equation of Table 2.9 with AAE = 0.855, AEA = 0.753.
(b) Find the dew point of the mixture.
(c) Does the mixture from an azeotrope? If so, predict the temperature and composition.

you give us the antoine equations for the 2 components... is PA* for ethyl acetate, and PB* for ethyl alcohol?

Ooops. I used A & B and the problem gave A & E.
My A is the same as theirs: ethyl acetate
My B is their E: ehtanol.
Thanks for pointing this out.
I fixed the hint on the course website.
Your slide says that there is template...where???

What slide ?
dr. ricker 8:26 PM:
I think you mean slides 13-15 in lecture #7.
Sorry, bud. No template :(
You can do it !
