Vapour pressure of pure acetone and chloroform at 328 K are 741.8 mm Hg and 632.8 mm Hg respectively. Assuming that they form ideal solution over the entire range of composition, plot `"P"_"total"`, `"P"_"chloroform"` and `"P"_"acetone"` as a function of `"x"_"acetone"`. The experimental data observed for different compositions of mixtures is:
| `bb(100 xx "x"_"acetone")` | 0 | 11.8 | 23.4 | 36.0 | 50.8 | 58.2 | 64.5 | 72.1 |
| `bb("P"_"acetone"//"mm Hg")` | 0 | 54.9 | 110.1 | 202.4 | 322.7 | 405.9 | 454.1 | 521.1 |
| `bb("P"_"chloroform"//"mm Hg")` | 632.8 | 548.1 | 469.4 | 359.7 | 257.7 | 193.6 | 161.2 | 120.7 |
Plot this data also on the same graph paper. Indicate whether it has a positive or negative deviation from the ideal solution.

Which solution has the lower freezing point? 10 g of methanol (CH3OH) in 100g g of water (or) 20 g of ethanol (C2H5OH) in 200 g of water.
For ideal solution the volume of mixing of the pure components to form the solution is ____________.
If two liquids A and B form minimum boiling azeotrope at some specific composition then ______.
Concentration terms such as mass percentage, ppm, mole fraction and molality are independent of temperature, however molarity is a function of temperature. Explain.
Why soda water bottle kept at room temperature fizzes on opening?
Assertion: When a solution is separated from the pure solvent by a semipermeable membrane, the solvent molecules pass through it from pure solvent side to the solution side.
Reason: Diffusion of solvent occurs from a region of high concentration solution to a region of low concentration solution.
On increase in pressure for dissociation ofN2O4 into NO2, equilibrium shift towards
Assertion (A): The enthalpy of mixing Δmix H is equal to zero for an ideal solution.
Reason (R): For an ideal solution the interaction between solute and solvent molecules is stronger than the interactions between solute-solute or solvent-solvent molecules.
