At `27^@C` latent heat of `I^-` fusion of a compound is `2.7xx10^3 J mol^(-1)`. Calculate the entropy change during fusion.

A

`9.77 JK^(-1) "mol"^(-1)`

B

`10.73 JK^(-1)"mol"^(-1)`

C

`2930 JK^(-1)"mol"^(-1)`

D

`108.5 JK^(-1)"mol"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A

Entropy , `DeltaS_(f) =(DeltaH_(f))/(T_(f))=("Fusion enthalpy")/("Temperature")`
`DeltaS_(f)=(2930 J "mol"^(-1))/(300 K)=9.77 JK^(-1) "mol"^(-1)`
