Which of the following combinations represents the individual reactions and the quantities needed to determine ΔHrxn for the overall reaction represented by the chemical equation above?
A. CS₂(I) + 3 O₂(g) → CO₂ (g) + 2 SO₂ (g) ΔH∘ = -1075 kJ
2 H₂O (I) + 2 SO₂ (g) → 2 H₂S(g) + 3 O₂(g) ΔH∘ = +1136kJ
B. CS₂(I) + 3 O₂(g) → CO₂(g) + 2SO₂(g) ΔH∘ = -1075 kJ
H₂O(I) + SO₂(g) → H₂S(g) + 3/2 O₂(g) ΔH∘ = +568kJ
C. CS₂(I) + 3 O₂(g) → CO₂(g) + 2SO₂(g) ΔH∘ = -1075 kJ
H₂S(g) + 3/2 O₂(g) → H₂O(I) + SO₂(g) = -568kJ
D. CS₂(I) + 3O₂(g) → CO₂(g) + 2 SO₂(g) ΔH∘ = -1075 kJ
2H₂H(g) + 3O₂(g) → 2H₂O(I) + 2SO₂(g) ΔH∘ = -1136kJ
