Consider three liquids: water, dilute aqueous solution of glucose, and dilute aqueous solution of NaCl . The aqueous solutions of glucose and NaCl are of the same molal concentrations. The vapour pressures (p) of the three liquids are plotted (not drawn to scale) as a function of temperature (T) in the figure below. The three values of pressure, p₁(=1 ~atm ), p₂ and p₃ and three temperatures T₁, T₂ and T₃ are indicat
Options
- ACurves X , Y and Z correspond to pure water, glucose solution and NaCl solution respectively.
- BThe temperatures T₁, T₂ and T₃ represent the boiling points of the solutions corresponding to the curves X , Y
- CThe pressures, p₁, p₂ and p₃ are related as 2 p₂=p₁+p₃ .
- DThe temperatures, T₁, T₂ and T₃ are related as 3 T₂=2 T₁+T₃ .
Correct answer
C. The pressures, p₁, p₂ and p₃ are related as 2 p₂=p₁+p₃ .
