For the reaction `2H_(2)O_((l)) rarr H_(3)O_((aq))^(+) + OH_((aq))^(-)`, the value of `Delta H` is

A

114.6 kJ

B

`-114.6kJ`

C

57.3kJ

D

`-57.3kJ`

Text Solution

Verified by Experts

The correct Answer is:
C
`H_(2)O rarr H^(+) + OH^(-)` is reverse of neutralization
`rArr Delta H = - (-57.3) = 57.3` kJ
