1.	Which of the following is are correct for an ideal binary solution of two volatile liquids (eg. Benzene and toluene) ?
Answer» Its vapour is always richer in the more volatile component ( compared to the liquid ) The liquid will gradually BECOME richer in the less volatile component if such as mixture is boiled (DISTILLED) The `p_T` (ie. The total pressure) above the solution will be the sum of the vapour pressures of the two PURE components The boiling point of the solution will be less than the boiling point of the two components Solution :(A)`(X'_A)/(X_B)=(P_A^@X_A)/(P_B^@X_B)` `(X'_A)/(X'_B)gt X_A/X_B ( "If" P_A^@ gt P_B^@)` (B)If `P_A^@` is more, more A will EVAPORATE more and B will stay BACK in the solution. (C )`P_T=P_A^@X_A+P_B^@X_BneP_A^@+P_B^@` (D)`If P_A^@ gt P_B^@` . Then `P_A^@ gt P_T gt P_B^@` `P_A^@ gt P_A^@X_A + P_B^@X_B gt P_B^@`.Hence boiling point of solution is more than A but less than B.
