Question

For the reaction
2 Fe₂O3 →→ 4 Fe +30₂ 
ΔHrxn = +824.2 kJ/mol
the decomposition of 14.0 g of Fe₂O3 results in
the absorption of 72.3 kJ of heat.
the release of 72.3 kJ of heat.
the absorption of 5770 kJ of heat.
the absorption of 36.1 kJ of heat.
the release of 36.1 kJ of heat.
the release of 5770 kJ of heat.
