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:

For the reaction 2H_(2(g)) + o_(2(g)) rarr 2H_(2)O_((g)), Delta H^(@)

1.	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:
Answer» 286.6kJ 573.2 KJ `-28.66` k Cal 68.56 kCal Solution :For DECOMPSITION `+573.2 rarr 2` mol ? `rarr` 1MOL `Delta = (573.2)/(2)` = 286.6kJ/mol = 68.56 Kcal/mol
