The heat of neutralization of LiOH and H...

The heat of neutralization of LiOH and `H_(2)SO_(4)` at `25^(@)`C is `69.6 KJ mol^(-1)`. Calculate the heat of innisation of LiOH will be nearly :-

A

`22.5KJmol^(-1)`.

B

`90 KJ mol^(-1)`.

C

`45KJ mol^(-1)`

D

`33.6KJmol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`2LiOH+H_(2)SO4toLi_(2)SO_(2)+2H_(2)SO_(4)O`
`Delta H_"(neut.)"=-69.6KJ//mol=2DeltaH_(ion)(LiON)+O-57.3xx2`
`DeltaH_(ioni(LiOH)=22.5KJ//mol`.
