Consider the following statements about the composition of the vapour over an ideal 1:1 molar mixture of benzene and toluene. The correct statement is:
Assume that the temperature is constant at 25 oC.
(Given, vapour pressure data at 25 °C, benzene = 12.8 kPa, toluene = 3.85 kPa)
| 1. | The vapour will contain a higher percentage of toluene. |
| 2. | The vapour will contain equal amounts of benzene and toluene. |
| 3. | Not enough information is given to make a prediction. |
| 4. | The vapour will contain a higher percentage of benzene. |
The electrolyte having the same value of Van't Hoff factor (i) as that of Al2(SO4)3 (if all are 100% ionized) is:
| 1. | K2SO4 | 2. | K3[Fe(CN)6] |
| 3. | Al(NO3)3 | 4. | K4[Fe(CN)6] |
