What is the entropy change (in J K

^{-1}

mol

^{-1}

) when one mole of ice is converted into water at

0^\circ C

? (The enthalpy change for the conversion of ice to liquid water is

6.0\ \text{kJ mol}^{-1}

0^\circ C

Step-by-Step Verified Solution

H 2 O(s) _ H 2 O(l) _ H = 6.0 kJ mol �1 T = 0 + 273 K = 273 K; _ S = ? _ S = _ H T = 6000 273 = 21.98 JK �1 mol �1
