A student is studying a temperature-composition diagram of a binary mixture of two pure substances, Kimium and Kallosium, at 1 atm. The molar mass of Kimium and Kallosium are 80 kg/kmol and 100 kg/kmol respectively. The substances are completely miscible, without any azeotrope at 1 atm. The student has obtained the following data from the diagram.

Case Mole % of Kimium Bubble point temperature (degrees C) Dew Point temperature (degrees C)
1 25 100 106
2 45 93 100

a) in an experiment, 1 kmol of liquid mixture of 30 mol% Kimium and remaining Kallosium is brought to an equilibrium temperature of 100 degrees Celsius at 1 atm.

i) how many phases are present?

ii) Find the amount of each phase in kmol.

iii) find the amount of each phase in kg.

b) How many phases will be present at equilibrium in a closed container filled with 25 mol Kimium and 75 mol Kallosium at 110 degree Celsius and at 1 atm?
