Question

All oxides of sulfur (SO, SO₂, and SO₃) have negative ΔG°_f at 25°C but only one oxide has a positive ΔH°_f at the same temperature. Identify the oxide and explain why its ΔH°_f is positive.

Accepted Answer

SO has a negative ΔHº_f since more bond breaking is involved.

Answer

SO₂ has a negative ΔHº_f since more bond breaking is involved.

Answer

SO₃ has a negative ΔHº_f since more bond breaking is involved.
