Question

Shown to the right is the solid-liquid phase
behavior for mixtures of component A and
component B at 1 atm. Use the phase diagram
to answer the following questions.

a) Specify the melting point of substance B at
1 atm

b) What is the maximum composition (mole fraction) of component B that
is possible for the mixture to exist in phase S2? At what temperature does this
occur?


c) 20mol of component A and 180mol of component B are mixed at
350°C and 1 atm. The mixture is cooled at constant pressure to 200°C.

i) What phases are present at the final state?

ii) What is the composition of each phase at the final state?
iii) What is the number of moles of each phase at the final state?
