Determine the heat of reaction if gamma iron is oxidized by pure oxygen to form FeO at 1350 oC. Use the following information: For FeO: = / {(, )} = . + . / {(,)} = . /(. ) {()} = . + . / < > = . + . . / () > = . + . . / At 770 oC, Fe(, ferromag) transforms to Fe(, paramag) = = + / At 910 oC, Fe(, paramag) transforms to Fe() = = + / The following reaction applies: (, ) + = < > (, ) + = < > () + = < >
