The entropy of fusion of water is 5.260 `cal//"mole" K` calculate the enthalpy of fusion of water ?

A

`10.52 Kcal// mol`

B

`0.525 K Cal//mol`

C

`2.225K Cal//mol`

D

`1.435 K Cal//mol`

Text Solution

Verified by Experts

The correct Answer is:
D
`H_(2)O(s)hArrH_(2)O(l)`
`DeltaG=DeltaH-TDeltaS`
`O=DeltaH-(273xx5.26)/(1000)`
`DeltaH=1.435KCal//mol`
