Question
Calculate the standard free energy change for the ionization: $HF$(aq) -> H+(aq) + F-(aq) from the following data: $HF$(aq) -> $HF$(g); δ G° = 23.9 kJ; $HF$(g) -> H(g) + F(g); δ G° = 555.1 kJ; H(g) -> H+(g) + e-; δ G° = 1320.2 kJ; F(g) + e- -> F-(g); δ G° = -347.5 kJ; H+(g) + F-(g) + aq -> H+(aq) + F-(aq); δ G° = -1513.6 kJ

Answer: B
💡 Solution & Explanation
Summing all steps: δ G° = 23.9 + 555.1 + 1320.2 - 347.5 - 1513.6 = +38.1 kJ.
