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 The figures shown below represent 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 the freezing point is A B V P bar V P bar Ice 270 273 Ice 1 Water Ethanol 1 I T K I I 270 273 Water T K Water Water Ethanol V P bar V P bar Ice Ice I I 1 271 273 T K 1 271 Water I Water Ethanol Water 1 IWater Ethanol 273 T K 2017
