One mole of ice is converted into water at `273K`. The entropies of `H_2O(s)` and `H_2O(l)` are `38.20` and `60.01Jmol^(-1)K^(-1)` respectively. The enthalpy change for the conversion is:A. `59.54 J mol^(-1)`B. `5954 J mol^(-1)`C. `595.4 J mol^(-1)`D. `320.6 J mol^(-1)`

Answer» Correct Answer - B
`DeltaG=DeltaH-TDeltaS`, at equilibrium
`DeltaG=0 :. DeltaH=TDeltaS`
Or `DeltaH=273xx(60.01-38.20)`
`=5954.13 J mol^(-1)`
