Question

The vapour pressure of pure CHCl3 and CH2 Cl2 are 200 and 41.5 atm respectively. The weight of CHCl3 and CH2 Cl2 are resepectively 11.9 g and 17 g. The vapour pressure of solution will be (A) 80.5 (B) 79.5 (C) 94.3 (D) 105.5

Tardigrade Admin · Accepted Answer

P0CHCl3 = 200 atm P0CH3Cl2 = 41.5 atm n = (11.9/119) n = (17/85) = .1 = .2 PT = P0AXA+ P0BXB =200×(0.1/.3) +(41.5+0.2/.3) =94.33

Q. The vapour pressure of pure CHCl₃ and CH₂ Cl₂ are 200 and 41.5 atm respectively. The weight of CHCl₃ and CH₂ Cl₂ are resepectively 11.9 g and 17 g. The vapour pressure of solution will be

80.5

79.5

94.3

105.5

P⁰_CHCl₃ = 200 atm P⁰_CH₃Cl₂ = 41.5 atm
n = $\frac{11.9}{119}$ n = $\frac{17}{85}$
= .1 = .2
P_T = P⁰_AX_A+ P⁰_BX_B
$= 200 \times \frac{0.1}{.3} + \frac{41.5 + 0.2}{.3}$
$= 94.33$
