If the melting point of ice is 0⁰C and latent heat of fusion is 5.46 kJ mol⁻¹, the entropy change for the conversion of 18 g of ice to water at one atmosphere is
Options
(a) 5.46 JK⁻¹
(b) 20 JK⁻¹
(c) 50 JK⁻¹
(d) 360 JK⁻¹
Correct Answer:
20 JK⁻¹
Explanation:
ΔS= ΔHf /T = 5.46 / 273 = 0.02 kJ K⁻¹ mol⁻¹ = 20 J K⁻¹ mol⁻¹.
