Pure water freezes at 273 K and 1 bar. The addition of 34.5 g of ethanol to 500 g of water changes the freezing point of the solution. Use the freezing point depression constant of water as 2 K kg mol–1. The figures shown below represents plots of vapour pressure (V.P.) versus temperature (T). [Molecular weight of ethanol is 46 g mol–1] Among the following, the option representing change in the freezing point is - [JEE(Advanced) 2017] (A) V . P . / b a r 1 271 273 T/K (B) V .
