Question

5. What is meant by "Fractionating column efficiency"? Under what conditions (with respect to the fractionating column and the liquid mixture to be separated) fractional distillation process should work well? 6. What is meant by "theoretical plate" of a fractional distillation column? 7. Find out the approximate mole fraction and %composition of the boiling liquid (on the liquid curve) corresponding to the vapor mixture at three points A, B, and C (on the vapor curve) in the following diagram when the following mole-fractions are allowed to boil: 0.50 chloroform/0.50 methanol-point A; 0.67 chloroform/0.33 methanol-point B); 0.80 chloroform/0.20 methanol-point C:

i need help with 7 & 8?

Answer 1

+) #Ans:- w The mole fraction (xci) of chloroform at the Vapoker carve point A - Xi = ni I total where, ni = Amount of a constituent in moles. retotal - The total amount of all constituent. - in a mixture. .:201 = 0.50/50 -1 :: % composition at point. A = 1x100=100% 16 the mole fraction of chloroform at the Napour curve point B > i = 0.98 - 10.4925 : % Composition at point B = 0.49254100 = 149.25 74] (C) The mole fraction of chloroform at the Vapour curre point c - 31= 0 0 = 10:25] 1. % composition at point c = 0.25 X 100 0.67 256 Scanned with CamScanner

B) An Azeotrope is the constant boiling mixture. It is mixture of two or more liquids. whose quantity can not be changed by simple distillation. There are two types of Azeotoops ire, minimum boiling azeotrope and maximum boiling azeotropes. A solution that shows greator positive deviation From Raoult's law forms minimum boiling azeotropes. @gi- Ethanol Iwater shows fue deviation Forms Raoult's law. because it contain scog wabout 95% ethanol CamScanner
