Question

Calculate the standard enthalpy change for the phase transition reaction of ice to water at a constant pressure of 1 atm, given the following information:- The standard enthalpy of fusion for ice is 6.01 kJ/mol.- The molar heat capacity of ice is 36.8 J/(mol K).- The molar heat capacity of liquid water is 75.3 J/(mol K).- The melting point of ice is 0°C.- The boiling point of water is 100°C.

Answer 1

To calculate the standard enthalpy change for the phase transition of ice to water at a constant pressure of 1 atm, we only need to consider the standard enthalpy of fusion for ice, as the other information provided is not relevant to this specific calculation.The standard enthalpy of fusion for ice is given as 6.01 kJ/mol. This value represents the energy required to convert 1 mole of ice at its melting point  0C  to liquid water at the same temperature and pressure.Since the phase transition is from ice to water, the standard enthalpy change for this reaction is simply the standard enthalpy of fusion for ice:H = 6.01 kJ/molTherefore, the standard enthalpy change for the phase transition reaction of ice to water at a constant pressure of 1 atm is 6.01 kJ/mol.
