The following picture shows a temperature-composition diagram for an ideal liquid solution of two components A and B, in which Raoult’s law is obeyed by both components. If a simple distillation were performed starting with a liquid of composition L5, what would be the approximate % composition of the first drop of distillate collected? Here is the picture and answer choices, but it's for L5 not L4 like in the Chegg question.
