Q. No.The plot of osmotic pressure \((\pi)\) vs concentration \((mol L^{-1})\) for a solution gives a straight line with slope 25.73 L bar mol-1. The temperature at which osmotic pressure measurement is done is: \((\text {Use} \left.\mathrm{R}=0.083 \mathrm{~L} \mathrm{bar} \mathrm{mol}^{-1} \mathrm{~K}^{-1}\right)\)
| 1. | 310°C | 2. | 25.73°C |
| 3. | 12.05 °C | 4. | 37°C |

The following solutions were prepared by dissolving 10 g of glucose (C6H12O6) in 250 ml of water (P1), 10 g of urea (CH4N2O) in 250 ml of water (P2) and 10 g of sucrose (C12H22O11) in 250 ml of water (P3). The decreasing order of osmotic pressures of these solutions is:
| 1. | P2 > P3 > P1 | 2. | P3 > P1 > P2 |
| 3. | P2 > P1 > P3 | 4. | P1 > P2 > P3 |
