For the reaction `2H_(2(g)) + o_(2(g)) rarr 2H_(2)O_((g)), Delta H^(@) = - 573.2 kJ`. The heat of decomposition of water per mol is:

A

286.6kJ

B

573.2 kJ

C

`-28.66` k Cal

D

68.56 kCal

Text Solution

Verified by Experts

The correct Answer is:
A, D

For decompsition `+573.2 rarr 2` mol
? `rarr` 1mol
`Delta = (573.2)/(2)` = 286.6kJ/mol = 68.56 Kcal/mol
