6.10 Calculate the enthalpy change on freezing of 1.0 mol of water at to ice at .
at .
Total enthalpy change is equal to the summation of all the energy required at three different stages-
(i) from to of 1 mol of water (water water )
(ii) from to of 1 mol of ice (water ice)
(iii) from to of 1 mole of ice (ice ice)
So, the total enthalpy change
Hence the total enthalpy change in the transformation process is 7.151 kJ/mol
