Consider these hypothetical chemical reactions:
1. A ⇌ B, ΔG = 12.0 kJ/mol
2. B ⇌ C, ΔG = -30.8 kJ/mol
3. C ⇌ D, ΔG = 8.60 kJ/mol
What is the energy, ΔG, for the overall reaction, A ⇌ D?
Express your answer with the appropriate units.
What can be said about the favorability of the overall reaction?
a) This reaction is thermodynamically favorable.
b) This reaction is thermodynamically neutral.
c) This reaction is thermodynamically unfavorable.
d) There is not enough information to determine thermodynamic favorableness.
