For a benzene–toluene system, do as follows, using the data from Table 26.1-1: a. At 378.2 K, calculate yA and xA using Raoult’s law. b. If a mixture has a composition of xA = 0.40 and is at 358.2 K and 101.32 kPa pressure, will it boil? If not, at what temperature will it boil and what will be the composition of the vapor that comes off first?
