Standard enthalpy
« on: October 21, 2012, 06:53:08 PM »
I am given: 2Fe+(3/2)->Fe2O3 ΔHf° =-824 kJ mol^-1
and also: 2FeO+(1/2)O2->Fe2O3 ΔH°=-280 kJ per mol

I have to find the standard enthalpy of formation ΔHf° of FeO

Can someone show me how to do this? I keep getting -544, but that was marked wrong.
