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. |
