Liquids A and B form an ideal solution in the entire composition range. At 350 K, the vapor pressure of pure A and pure B are \(7 \times 10^{3}\) Pa and \(12 \times 10^{3}\) Pa, respectively. The composition of the vapour in equilibrium with a solution containing 40 mole percent of A at this temperature is:
- xA = 0.37; xB = 0.63
- xA = 0.28; xB = 0.72
- xA = 0.76; xB = 0.24
- xA = 0.4; xB = 0.6
Answer
(C) x A = 0.76; x B = 0.24
