lab. IS. E of A (M-/mul und 2.0 t B (M-115 pinol was mixed ut 25 "C. Tie mixture was heuted up to 90 C Show on diagram the point that represents the above Eystem heating At what temperature does the above me mu to bolly What la the composition of the first gas bubble? What is the boiling point of pure A and that of pure B7 What is the composition of the sotopic point? A given A-B misture was found to boll st 95. What is the composition of the gas and liquid pluss 7 d B Write true or false and explain your answer Ai 98 "C, the vapour pressure of pare A is higher than thuit of pure B. The interaction (altraction forces) between the A and B molecules in the mixture is larger than that between the A molecules in pure A and that between the molecules in pus D. c. The speration of the above mixture into purs A and B can be achieved simply by fractional distillation at 1 atm. d The above system represents a negative deviation from Raoulu law, Draw the P-X-diagram that corresponds to the given T-X diagram For Benzoic acid, Ka-6,5 x 10" WoW 1. 2.
