Reaction 1: 4 NH3(g) + 5 O2(g) -> 4 NO(g) + 6 H2O(l) dG° = -1010 kJ/mol_rxn Reaction 2: 2 NO2(g) -> Thermodynamics Chemistry Question

Question

Reaction 1: 4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(l) dG° = -1010 kJ/mol_rxn
Reaction 2: 2 NO2(g) → 2 NO(g) + O2(g) dG° = 70 kJ/mol_rxn
Reaction 3: 4 NO2(g) + O2(g) + 2 H2O(l) → 4 HNO3(aq) dG° = -170 kJ/mol_rxn

Based on the values of dG° for the three reactions represented above, what is the value of dG° for the reaction represented below?

4 NH3(g) + 8 O2(g) → 4 HNO3(aq) + 4 H2O(l)

A.

-1040 kJ/mol_rxn

B.

-1110 kJ/mol_rxn

C.

-1250 kJ/mol_rxn

D.

-1320 kJ/mol_rxn
