The figure shows the phase diagram of a non-ideal mixture of carbon tetracholoride (component 1) and acetone (component 2).   (i) What is the temperature of a constant boiling (azeotropic) mixture.   (ii) What is the boiling point temperature of a liquid mixture containing 80% carbon tetrachloride at 1 bar pressure (to the nearest degree K).   (iii) The same mixture is heated to a temperature of 340K. What is the composition of the liquid and vapor phases?   (iv) What is the vapor fraction at 340K; i.e. the fraction of the total number of moles in the vapor phase.
