Calculate the enthalpy of reaction for the following reaction: Question 19 Not yet answered Marked out of 1.00 Fe2O3(s) + 3CO(g) – 2Fe(s) + 3C02(9) P Flag question AH °(Fe2O3(s)) = -824.2 kJ/mol AH°(CO(g)) = -110.5 AH°(Fe(s)) = ? AH°(CO2(g)) = -393.5 kJ/mol Answer:
Calculate the enthalpy of reaction for the following reaction: 2Fe2O3(s) + 3C(s) → 4Fe(s) + 3CO2(g) ΔHfo(Fe2O3(s)) = -824.2 kJ/mol ΔHfo(C(s)) = ? ΔHfo(Fe(s)) = ? ΔHfo(CO2(g)) = -393.5 kJ/mol
Calculate ΔSo in J/K for the following reaction: 2Fe2O3(s) + 3C(s) → 4Fe(s) + 3CO2(g) So(Fe2O3(s)) = 87.4 J/K/mol So(C(s)) = 5.7 J/K/mol So(Fe(s)) = 27.3 J/K/mol So(CO2(g)) = 213.7 J/K/mol
2.Calculate the enthalpy of reaction for the following reaction: Fe2O3(s) + 3CO(g) → 2Fe(s) + 3CO2(g) ΔHfo(Fe2O3(s)) = -824.2 kJ/mol ΔHfo(CO(g)) = -110.5 ΔHfo(Fe(s)) = ? ΔHfo(CO2(g)) = -393.5 kJ/mol

Question 6 Not answered Marked out of 1.00 If the above reaction could be done at 3399 K, what would be your estimate for AGº (in kJ) at this elevated temperature? Use AG° =AH° -TAS® and assume AH° and 4Sº are independent of temperature. P Flag question (Theº is included because it is still for standard conditions, that is, 1 atm for gases and 1 molar for concentrations.) Answer: What is Agrº (in kJ) at 2268 K for the following...
