The enthalpy of fusion of water is 1.435 kcal/mol.The molar entropy change for the melting of ice at 0⁰C is

Options

(a) 10.52 cal/(mol-K)
(b) 21.01 cal/(mol-K)
(c) 5.260 cal/(mol-K)
(d) 0.526 cal/(mol-K)

Correct Answer:

5.260 cal/(mol-K)

Explanation:

ΔHf = 1.435 kcal/mol,
ΔS = ΔHf/Tf = 1.435 * 10³ / 273 = 5.26 cal/mol K.
