The Kw of water at two different temperature is :
`T" "25^@C" "50^@C`
`K_w" "1.08 xx 10^(-14)" "5.474 xx 10^(-14)`. Assuming that `triangleH` of any reaction is independent of temperature, calculate the enthalpy of neutralization of strong acid and strong base.

A

`triangleH_(neut)=-89.963" kJ mol"^(-1)`

B

`triangleH_(neut)=-67.967" kJ mol"^(-1)`

C

`triangleH_(neut)=-62.693" kJ mol"^(-1)`

D

`triangleH_(neut)=-51.963" kJ mol"^(-1)`
