(Answered) 1 calculate the standard enthalpy change for the following

Academics

1. Calculate the standard enthalpy change for the following chemical equation, using the supplied reactions below.

4FeO(s) + O2(g) ? 2Fe2O3(s)

and heat-of-formation data:

Fe + 0.5O2(g) ?FeO ΔH = -269 kJ/mol

2Fe + 1.5O2(g) ?Fe2O3 ΔH = -825 kJ/mol

2. Use the standard enthalpies of formation from the GChem Thermodynamic Data Tables to calculate the standard reaction enthalpy of the following reaction:

SO2 (g) + ½ O2 (g) → SO3 (g)
