Q. Molar heat capacity of water in equilibrium with ice at constant pressure is:- a) zero b) infinity c) 40.4 `kJ mol^-1 K^-1` d) 75.4 `kJ mol^-1 K^-1`
Water, in equilibrium with ice has a steady temperature of zero degree Celsius.
Water, in the liquid state, has a specific heat of exactly 1 calorie per gram.
Molar mass of water is 15.999+2.016=18.015 grams per mole.
Therefore, molar heat capacity of water at zero degree Celsius is
None of the given options is correct.
