Prove that a straight line from the apex A of a ternary phase diagram to the opposite edge BC represents mixtures of constant ratio of B and C, however much A is present.

On a single-component phase diagram, one must cross a coexistence line to move from the region for liquids to the region for gases. True False

The binary water-phenol diagram is given below, in molar fraction, under the total pressure Pt = 1 atm. 1) How many phases are there in the domain marked "I"? 2) From which temperature the mixture become miscible in all proportions? How do you call that temperature? 3) At a temperature T = 50 °C, in a controlled temperature container containing water. Phenol is then poured at the same temperature until the molar fraction of phenol in the mixture XC2H50H is equal to 0.05. Then, we continue to add the phenol gradually, at a constant temperature, to XC2H5OH of phenol in the mixture is XC2H5OH = 0.8. = 0.4. Then finally we stop adding phenol when the molar fraction a. How many phases are present at each one of the three mixture compositions in the container during the addition of the phenol? b. What is the composition of the phases when the fraction of phenol is XC2H5OH = 0.4? c. What is the proportions of the phases with respect to each other when XC2H5OH = 0.4? (Show your calculations)…
