Question

If a solute, whose vapor pressure is 800 Torr, forms an azeotropic mixture with a solvent at 1 atm when its liquid mole fraction is 0.45 its activity coefficient exceeds 1.0. For a mixture of three components and two phase, the number of independent variables which uniquely define this multiphase and multicomponent system is two The slope of the chemical potential vs. temperature graph of liquid propane is more steep than that of gaseous propane. Based on the attached graph, the enthalpy of condensation Is more negative than 10 kJ/mol. Based on the attached graph, the activity coefficient of the more volatile component does not exceed 1.2 when its mole fraction is 0.25. Based on the attached graph, the Henry's law constant of the more volatile component does not exceed that of the less volatile component by more than 50%.

Explanation / Answer

2) F = C - P + 2

Given that C = 3, P = 2

Then,

F = 3 - 2 + 2 = 3

Hence,

no of degree of freedom = no of indepenent variables = 3

Therefore,

Given statement is FALSE.
