The change in entropy for the fusion of 1 mole of ice is [mp of ice (=273 ~K ), molar enthalpy of fusion for ice (=6.0 ~kJ ~mol ⁻¹ ) ]
Options
- A(11.73 JK ⁻¹ ~mol ⁻¹ )
- B(18.84 JK ⁻¹ ~mol ⁻¹ )
- C(21.97 JK ⁻¹ ~mol ⁻¹ )
- D(24.47 JK ⁻¹ ~mol ⁻¹ )
Correct answer
C. (21.97 JK ⁻¹ ~mol ⁻¹ )
Step-by-step solution
Entropy change of fusion ( gathered S_f= H_f T H_f=60 10^3 ~J , ~mol ⁻¹, T=273 ~K S_f= 60 10^3 273 =21.97 ~J ~K ⁻¹ ~mol ⁻¹ gathered )
