If the heat fo dissolution of anhydrous ...

If the heat fo dissolution of anhydrous `CuSO_(4)` and `CuSO_(4).5H_(2)O` is `-15.89 kcal` and `2.80 kcal`, respectively, then the heat of hydration of `CuSO_(4)` to form `CuSO_(4).5H_(2)O` is

A

`-13.09` kcal

B

`-18.69` kcal

C

`+13.09`kcal

D

`+18.69` kcal

Text Solution

Verified by Experts

The correct Answer is:
B

(i) `CuSO_4+aqto CuSO_4(ag)DeltaH_1=-1589kcal`
(ii) `CuSO_4.5H_2O+aqtoCuSO_4(aq)DeltaH_2=+2.8kcal`
Eq.(i) -Eq.(ii) gives
`DeltaH=-1869kcal (DeltaH=DeltaH_1-DeltaH_2)`
