The enthalpy change on freezing of 1 mol of water at 5oC to ice at −5oC is : (Given $\Delta $fusH = 6 kJ mol$-$1 at 0oC, Cp(H2O, $\ell $ = 75.3J mol$-$1 K$-$1) Cp(H2O s) =36.8 J mol$-$1 K$-$1)

Question

The enthalpy change on freezing of 1 mol of water at 5^oC to ice at −5^oC is :

(Given $\Delta $_fusH = 6 kJ mol^$-$1 at 0^oC,
C_p(H₂O, $\ell $ = 75.3J mol^$-$1 K^$-$1)
C_p(H₂O s) =36.8 J mol^$-$1 K^$-$1)

5.44 kJ mol^$-$1

5.81 kJ mol^$-$1

6.56 kJ mol^$-$1

6.00 kJ mol^$-$1
