$p_{A}^{\circ}$ and $p_{B}^{\circ}$ are the vapour pressures of pure liquid components A and B, respectively, of an ideal binary solution. If $x_{A}$ represents the mole fraction of component A, the total pressure of the solution will be
- A$p_{B}^{\circ}+x_{A}(p_{B}^{\circ}-p_{A}^{\circ})$
- B$p_{B}^{\circ}+x_{A}(p_{A}^{\circ}-p_{B}^{\circ})$
- C$p_{A}^{\circ}+x_{A}(p_{B}^{\circ}-p_{A}^{\circ})$
- D$p_{A}^{\circ}+x_{A}(p_{A}^{\circ}-p_{B}^{\circ})$
✓ Correct answer: B
