DeltaS for freezing of 10 g of H(2)O(l) ...

`DeltaS` for freezing of 10 g of `H_(2)O(l)` (enthalpy of fusion is 80 cal/g) at `0^(@)C` and 1 atm is :

A

`12.25 J//K`

B

`-0.244 J//K`

C

`-2.93 J//K`

D

`-12.25 J//K`

Text Solution

Verified by Experts

The correct Answer is:
D
`DeltaS_("freezing ")=-(DeltaH_("fusion"))/(T)`
`implies" "DeltaS=-(80xx10)/(273)xx4.18`
`=-12.25 J//K`
