Question
The vapour pressure of the solution of two liquids A(po = 80 mm) and B(po = 120 mm) is found to be 100 mm when xA = 0.4. The result shows that
Options
A.solution exhibits ideal behaviour
B.solution shows positive deviations
C.solution shows negative deviations
D.solution will show positive deviations for lower concentration and negative deviations for higher concentrations.
Solution
PTotal = 0.4 × 80 + 0.6 × 120 = 104 > 100 mm of Hg.
