Question

A liquid mixture containing 25 mole % methanol and 75 mole % water, which
components are miscible in all proportions, is heated at a constant pressure of 1 atm from
a temperature of 60 0 C to 100 0 C. Using the following experimental T-x-y data, answer
the following questions

(a) Construct a T-x-y diagram for the system. Use this diagram to help you answer the
following questions.
(b) Does this system form an azeotropic mixture? Do you think Raoult’s law can predict
the vapour liquid equilibrium behavior of this system? Why?
(c) At what temperature does vaporization begin?
(d) What is the composition of the first bubble formed of the equilibrium vapour?
(e) What is the temperature required to evaporate 25 mol% of the liquid mixture? What is
the composition of the residual liquid? Assume that the entire vapour formed is retained
in the apparatus and that it is completely mixed and in equilibrium with the residual
liquid.
(f) What is the composition of the residual liquid and vapour when 90 mol% of the liquid
mixture is vapourized?

Answer 1

Answer:

composition of residual required and Bappa when 90% picture is vaporized 25 mole percentage of liquid mixture composition of liquid at home the entire were performed is retained in the apertures and that is compact Sony Mix and inequality
