At 300 K , the vapour pressure of toluene and benzene are 3.63 kPa and 9.7 kPa respectively. What is the composition of vapour in equilibrium with the solution containing 0.4 mole fraction of toluene? (Assume the solution is ideal)
- A \(0.40\)
- B \(0.60\)
- C \(0.80\)
- D \(0.20\)
Answer & Solution
Correct Answer
(D) \(0.20\)
Step-by-step Solution
Detailed explanation
\begin{aligned} & \text { } \mathrm{P}_{\mathrm{T}}^0=3.63 \mathrm{kPa} \quad \mathrm{X}_{\mathrm{A}}=0.4 \quad\left[\mathrm{X}_{\mathrm{A}}+\mathrm{X}_{\mathrm{B}}=1\right] \\ & \mathrm{P}_{\mathrm{B}}=9.7 \mathrm{kPa} \quad \mathrm{X}_{\mathrm{A}}=0.6 \\ & \therefore…
