Real Binary Solid Solutions

GATE MT 2017 Q32. Pure metals A and B form two real binary solid solutions α and β at a temperature T and pressure P. The free energy versus composition plots for both the solutions are given below. The condition for chemical equilibrium is:

16%(A) Mole fraction of A in α=mole fraction of A in βand mole fraction of B in α= mole fraction of B in β ( 4 voters )

12%(B) Mole fraction of B in α= mole fraction of A in β and mole fraction of A in α = mole fraction of B in β ( 3 voters )

60%(C) Activity of A in α= activity of A in β and activity of B in α=activity of B in β ( 15 voters )

12%(D) Activity of A in α= activity of B in β and activity of B in α= activity of A in β ( 3 voters )
