(a) Derive a relationship between the elevation in boiling point of a solution and the mole fraction of the solute from the thermodynamic consideration.
(b) The molal elevation constant (Kb) and the boiling point for CCl4 are 5.02 deg/moll and 76.80C respectively. Calculate the boiling point of 1.0 molal solution of naphthalene in carbon tetrachloride. 2+3 = 5
Q. Draw a vapour pressure composition diagram for an ideal binary solution obeying this law and compare this with similar diagram showing derivation from Raoult's law. Why do these deviations occur?
Q. Draw a phase diagram for the CO2 system using the following data:
