Vedclass · Answer

(C) The process of melting ice at $0 \ ^\circ C$ $(273 \ K)$ is a reversible phase transition.For a reversible process,the entropy change is given by $\Delta S = \frac{\Delta H_{fus}}{T}$.Given $\Delta H_{fus} = 1.435 \ kcal/mol = 1435 \ cal/mol$.Temperature $T = 0 \ ^\circ C = 273 \ K$.Therefore,$\Delta S = \frac{1435 \ cal/mol}{273 \ K} = 5.256 \ cal/(mol \ K) \approx 5.26 \ cal/(mol \ K)$.

The enthalpy of fusion of water is $1.435 \ kcal/mol$. The molar entropy change for the melting of ice at $0 \ ^\circ C$ is
