81. If a binary system exihibits a miscibility gap in the solid state, then the enthalpy of mixing in the solid state, ΔHmix should necessarily be
82. The vapour pressure of a solid M varies with temperature T in K, as
In p(atm) = $$frac{{ - 33,200}}{T}$$ - 0.85 In T + 21.46
The vapour pressure of liquid M varies with temperature T, in K, as
In p (atm) $$frac{{ - 33,200}}{T}$$ = 0.85 In T + 20.31
The temperature of the triple point of M, in K is
In p(atm) = $$frac{{ - 33,200}}{T}$$ - 0.85 In T + 21.46
The vapour pressure of liquid M varies with temperature T, in K, as
In p (atm) $$frac{{ - 33,200}}{T}$$ = 0.85 In T + 20.31
The temperature of the triple point of M, in K is
