Heat of neutralisation of `NaOH` and `HCl` is `-57.46 kJ //` equivalent. The heat of ionisation of water in `kJ //mol` is `:`

A

`-57.46`

B

`+57.46`

C

`-114.92`

D

`+114.92`

Text Solution

Verified by Experts

The correct Answer is:
B
`H^(+)+OH^(-)rarr H_(2)O, DeltaH=-57.46kJ //eq.`
`(` heat of neutralisation `)`
`H_(2)O rarr H^(+)+OH^(-), DeltaH=57.46kJ//eq. or kJ //mol`
