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 Ptotal, `P_"chloroform"` and `P_"acetone"` as a function of `chi_"acetone"`. The experimental data observed for different compositions of mixtures is:
| `bb(100 xx chi_"acetone")` | `bb(P_"acetone"//"mm Hg")` | `bb(P_"chloroform"//"mm Hg")` |
| 0 | 0 | 632.8 |
| 11.8 | 54.9 | 548.1 |
| 23.4 | 110.1 | 469.4 |
| 36.0 | 202.4 | 359.7 |
| 50.8 | 322.7 | 257.7 |
| 58.2 | 405.9 | 193.6 |
| 64.5 | 454.1 | 161.2 |
| 72.1 | 521.1 | 120.7 |
