Fe2O3(s) + 3 CO(g) → 2 Fe(s) + 3 CO2(g) In the preceding reaction, _____ is in elemental form and has a standard enthalpy of ______ . This reaction is a ______ reaction (think heat). The standard enthalpy for the reaction is _______ kJ (3 S.F.)

Solutions

Expert Solution

Fe is in elemental form and has 0 kJ of standard enthalpy of formation.

The reaction Exothermic reaction

Fe2O3(s) + 3 CO(g) → 2 Fe(s) + 3 CO2(g)

H0rxn = 2 H0f (Fe) + 3 H0f (CO2) - H0f(Fe2O3) - 3 H0f (CO)

H0rxn =2 (0) + 3 ( - 393.5) - ( - 822.2) - 3 ( - 110.5)

H0rxn =- 26.8 kJ
