Answer: Option 2
Given, vapor-liquid equilibrium : Number of components \[\left( {{\rm{water}}} \right) = 1\] Number of phases involved \[\left( {{\rm{vapor - liquid}}} \right) = 2\] So, degree of freedom : \[\begin{array}{l} \left( f \right) = C - \emptyset + 2\\ 1 - 2 + 2 = 1 \end{array}\]

What is the number of degrees of freedom for liquid water in equilibrium with a mixture of nitrogen and water vapor?
Answer: Option 1 Given, number of components $$= 2$$ Number of phases $$= 2$$ $$\eqalign{ & {\text{So, }}f = 2 - 2 + 2 \cr & \Rightarrow f = 2 \cr} $$ Assuming no reaction...

When liquid and vapour phase of multi-component system are in equilibrium (at a given temperature and pressure), then chemical potential of each component is?
Answer: Option 1 For thermodynamic equilibrium to satisfy by a system the system should satisfies three conditions I. Temperature should be same between the phases. II. Pressure should be same between...

When liquid and vapour phases of one component system are in equilibrium (at a given temperature and pressure), the molar free energy is?
Answer: Option 3 If the liquid and vapor are pure, in that they consist of only one molecular component and no impurities, then the equilibrium state between the two phases...
