A binary solution contains `x_1 and x_2` mile fraction of two components having vapour pressure `p_1^@ and p_2^@` in this pure states. The total vapour pressure above the solution is

If mole fraction of a solvent is 0.25 and its vapour pressure in pure state is 150mlmm, find the vapour pressure of the solution.

The mole fraction of component A in vapour phase is y_1, and mole fraction of component A in liquid mixture is x_1 (P_A^@ "=vapour pressure of pure A, P"_B^@="vapour pressure of pure B"). Then total vapour pressure of the liquid mixture is

An ideal solution is prepared from A and B (both are volatile). The composition of the solution is such that the total vapour pressure is harmonic mean of vapour pressures of pure A(P_(A)^(@)) and pure B(P_(B)^(@)).[P_(A)^(@) ne P_(B)^(@)] If x_(A), x_(B) represents mole freaction of A and B in solution respectively and y_(A) and Y_(B) represents mole fraction of A and b in vapour phase, then answer the following questions. If the total vapour pressure is half the value mentioned in the above comprehension, then which of the following must be ture?

At a given temperature if P is the vapour pressure of a solution and P_0 that of its pure solvent , the relative lowerning of vapour pressure of the solution is given by :

Read the passage given below and answer the following questions : Raoult's law states that for a solution of volatile liquids, the partial vapour pressure of each component of the solution is directly proportional to its mole fraction present in solution. Dalton's law of partial pressure states that the total pressure P_("total") over the solution phase in the container will be the sum of the partial pressures of the components of the solution and is given as: P_("total") = P_1 + P_2 Which of the following aqueous solutions should have the highest boiling point ?
