The following is a T-x-y phase diagram for a binary system at constant pressure. a) Calculate the degrees of freedom (F) for the points represented by ‘c’ and ‘P’. Explain the significance of F in each case. b) An organic compound X is commonly used in commercial antifreeze agents, such as radiator fluids. Calculate the freezing point of a solution of 400 g of X in 500 g water. (Kf for water is -1.86 0C.m-1 and freezing point of pure water = 0oC)

Question
The following is a T-x-y phase diagram for a binary system at constant pressure.
a) Calculate the degrees of freedom (F) for the points represented by ‘c’ and ‘P’. Explain the significance of F in each case.
b) An organic compound X is commonly used in commercial antifreeze agents, such as radiator fluids. Calculate the freezing point of a solution of 400 g of X in 500 g water. (Kf for water is -1.86 0C.m-1 and freezing point of pure water = 0oC).
c) When a solution of 1.00 g of A in 100 cm3 of water was shaken with 10 cm3 of organic solvent (S), 0.80 g of A was transferred to the ether layer. How much of A would be extracted using 5 cm3 of S instead of 10 cm3?
