Calculate the standard enthalpy change for the phase transition reaction, where 1 mole of solid water (ice) is transformed into 1 mole of liquid water at a constant pressure of 1 atm and a temperature of 298 K. Given the specific heat capacity of ice is 2.108 J g^-1 K^-1 and the specific heat capacity of water is 4.184 J g^-1 K^-1. The molar enthalpy of fusion of water is 6.01 kJ/mol.
