1.	Two compounds A and B in when mixed form nearly ideal solutions. At room temperature, P0A=40 mm Hg and P0B=120 mm Hg.A liquid mixture is composed of 1 mol of A and 3 mol of B. When the first trace of vapour is formed, choose the correct option(s) regarding composition of A and B in vapour phase :Here,yA=Composition of A in vapour phase when first trace of vapour is formedyB=Composition of B in vapour phase when first trace of vapour is formed
Answer» Two compounds A and B in when mixed form nearly ideal solutions. At room temperature, $P_{A}^{0} = 40 m m H g$ and $P_{B}^{0} = 120 m m H g$ . A liquid mixture is composed of $1 m o l$ of A and $3 m o l$ of B. When the first trace of vapour is formed, choose the correct option(s) regarding composition of A and B in vapour phase : Here, $y_{A} = Composition of A in vapour phase when first trace of vapour is formed$ $y_{B} = Composition of B in vapour phase when first trace of vapour is formed$
