What is the entropy change (in JK−1 mol−1\mathrm{JK}^{-1} \mathrm{~mol}^{-1} ) when one mole of ice is converted into water at 0∘C0^{\circ} \mathrm{C} ? (The enthalpy change for the conversion of ice to liquid water is 6.0 kJ mol−16.0 \mathrm{~kJ} \mathrm{~mol}^{-1} at 0∘C0^{\circ} \mathrm{C} )

Options

  1. A20.13
  2. B2.013
  3. C2.198
  4. D21.98

Correct answer

D. 21.98

Step-by-step solution

S=qrev T=6000273\mathrm{S}=\frac{q_{r e v}}{\mathrm{~T}}=\frac{6000}{273} =21.978=21.98JK−1 mol−1.=21.978=21.98 \mathrm{JK}^{-1} \mathrm{~mol}^{-1}.
