The standerd enthalpy of formation of Fe...

The standerd enthalpy of formation of FeO and `Fe_(2)O_(3)` is `-65` kcal `"mole"^(-1)` and `-197 " kcal" " mole"^(-1)` respectively . A mixture of two oxides containes FeO and `Fe_(2)O_(3)` in the mole ratio `2 : 1` . If by oxidation, it is changed into a `1 : 2` mole ratio mixture , How much of thermal energy will released per mole of the internal mixture ?

A

`13.4 kcal//"mole"`

B

`14.6 kcal//"mole"`

C

`15.7 kcal//"mole"`

D
