S₈(g) + 8 O₂(g) → 8 SO₂ (g) ΔH°_f = -2476.7 kJ/mol

S(s) + O₂(g) → SO₂ (g) ΔH°_f = -296.8 kJ/mol

S₂(g) + 2 O₂(g) → 2 SO₂ (g) ΔH°_f = -722.2 kJ/mol

S(g) + O₂(g) → SO₂ (g) ΔH°_f = -574 kJ/mol

Give the equation for the formation of SO2(g) from the standard states of its elements and determine its ΔH°f
