Question
An equimolar amount of acetone(1) and acetonitrile(2) has been through a process to pressure ofP and temperature of T and conforms closely to Raoult's Law. a) Determine the temperature at which the phases exist as saturated vapor in equilibrium at P 50 kPa with minimum trial ofONE ONLY. (11 Marks) b) Determine the liquid fraction (by mol) in equilibrium at a condition as stated in part (a) c) Show the points mentioned in parts (a) and (b) on Figure 1, label the figure and attach the figure to your answer script. (3 Marks) d) Prove that part (a) can be determined using Raoult's Law and based on the definition of K-value. (9 Marks)Explanation / Answer
Since the two components are behaving as ideal in solution so there vapours will also form an ideal gas so we can applied ideal gas equation conveniently to arrive at temperatures correspond to pressure 50 kpa at which the two components exit in saturated vapour state .Now by applying ideal gas equation correspond to 50 kpa .we come across no of moles of each components equal to 1/2 .Now by applying ideal gas equation we come to term with temperatures for the state being ask.
B. As we have just above calculated the no of moles eual to 1/2 for both components in vapour state so the no of moles of both components in liquid fraction would also be 1/2.
