Question

at its melting point, O c, the enthalpy of fusion of water is 1.435 kcal/mol. what is the molar entropy change for the melting ice at 0C?

answer: 5.26 cal/mol-k

Answer 1

dG = dH - TdS
At the melting point of zero C the system is in equilibrium; therefore, dG = 0. Substitute and solve for dS.

Answer 2

so dH/T?
