Which of the following formula represents Raoult's law for a solution containing non-volatile solute?(A) Psolute = Posoulte . Xsolute(B) P = KH.x(C) PTotal = Psolvent(D) Psolute = Posolvent . Xsolvent |

Answer» Option : (B) P = KH.x Solution which have only one volatile components, The vapour pressure of volatile component in a given solution can be written by - P1 = x1\(P_1^0\) If we compare the equations for Raoult's law and Henry's law, (P = KH.x), only proportionality constant KH differes from \(P_1^0\). Thus, Rault's law becomes a special case of Henry's law in which KH becomes equal to \(P_1^0\). All other options are wrong for Roult's law. |
