At $27^\circ C$ latent heat of fusion of a compound is 2930 J/mol. Entropy change is :
A 9.77 J/mol K
B 10.77 J/mol K
C 9.07 J/mol K
D 0.977 J/mol K

Detailed Solution

For fusion at the melting point: $\Delta S = \dfrac{\Delta H_{fus}}{T}$
$T = 27 + 273 = 300$ K
$\Delta S = \dfrac{2930}{300} = 9.77$ J/mol K
