The vapor-liquid composition curve for a two component liquid mixture is shown below. Use the diagram to determine which of the following statements are true. A. A and B have boiling points of 85 A degree C and 91 A degree C. B. A and B have boiling points of 82 A degree C and 101 A degree C. C. Point b represents the temperature at which a 40:60 mixture of A:B begins to boil. D. The line from a to b is the line that ties the vapor composition to the liquid composition at that temperature.Explanation / Answer
A)FALSE
B)TRUE
C)FALSE
D)TRUE
boiling occurs when pressure of a component equals the total pressure of the system this happens in pure phase of a & b i.e at 82C and 91C
point b corresponds to some other point which is not 40 & 60% of a and b
line between a and b ties to the vapor composition to the liquid composition at the same temperature
