Calculate the enthalpy for the reaction 2Fe(s) + 3/2O2(g) -> Fe2O3(s) from the following: 2FeO(s) +1/2O2(g) -> Fe2O3(s) H= -280 kJ 2Fe(s) + O2(g) ->
Calculate the enthalpy for the reaction 2Fe(s) + 3/2O2(g) -> Fe2O3(s) from the following:
2FeO(s) +1/2O2(g) -> Fe2O3(s)
H= -280 kJ
2Fe(s) + O2(g) -> 2FeO(s)
H= -544 kJ
