For parts of the free response question that require calculations,D. ΔG = 170. kJ/mol; The reaction is NOT thermodynamically favorable. Answer: Using ΔG = ΔH - TΔS, one finds that ΔG = 170 kJ/mol. Since ΔG is a positive number, this indicates that the reaction is not thermodynamically favorable. 📄 Study AP Chemistry, Unit 9.3: Gibbs Free Energy and Thermodynamic Favorability. 4.Ap Physics 1 Unit 1 Progress Check Flashcards | Quizlet.
