What will be the heat of reaction for the following reaction? Will the reaction be exothermic or endothermic?
Fe2O3(s) + 3H2(g)→ 2Fe(s) + 3H2O(l)
DfH° (H2O,l) = –285.83 kJ mol–1, Df H°(Fe2O3,s) = – 824.2 kJ mol–1
Fe2O3(s) + 3H2(g)→ 2Fe(s) + 3H2O(l)
DfH° (H2O,l) = –285.83 kJ mol–1, Df H°(Fe2O3,s) = – 824.2 kJ mol–1
- –824.2 kJ mol–1, exothermic
- +33.3 kJ mol–1, endothermic
- –33.3 kJ mol–1, exothermic
- +824.2 kJ mol–1, endothermic
Answer
(C) –33.3 kJ mol –1 , exothermic
