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

`286.6 kJ`

B

`573.2 kJ`

C

`-28.66 kJ`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
A
Heat of decomposition of water is `H_2O_(g) to H_(2)(g) + 1/2 O_(2)(g) Delta H = (+573 .2)/(2) = 286.6 kJ//mol`.
