Question

Consider the following reaction: 4 NH₃(g) + 7 O₂(g) → 4 NO₂(g) + 6 H₂O (l) ΔG°f -16.7 0.0 51.8 -237.2 kJ/mol What is ΔG° for this reaction in kJ? A) -1282 B) -1149 C) -169 D) 169 E) 1149

Quizplus · Accepted Answer

ΔG° = ΣΔG°f(products) - ΣΔG°f(reactants)
= [4(51.8 kJ/mol) + 6(-237.2 kJ/mol)] - [4(-16.7 kJ/mol) + 7(0 kJ/mol)]
= -1149 kJ
