Iron(II) oxide vs iron(III) oxide in a thermite reaction

  1. Jan 30, 2013 #1
    hey guys
    i am wondering what the difference between using Fe2O3 or FeO would be in a thermite reaction to produce aluminium oxide.
    wouldn't the FeO produce a more energy since its enthalpy of formation is lower?

    thanks for your answers!

    I am not sure about this but did you check out the ellingham diagram? This might give you the answer.
