For the reaction,
`2H_(2)(g)+O_(2)(g) to 2H_(2)O(g), DeltaH=-573.2kJ`
The heat of decomposition of water per mole

A

286.6kJ

B

573.2kJ

C

-28.66kJ

D

zero

Text Solution

Verified by Experts

The correct Answer is:
A
Heat of decomposition of water is
`H_(2)O(g) to H_(2)(g)+(1)/(2)O_(2)(g)`
`DeltaH=(+573)/(2)=296.6kJ//mol`
