Question

Study the following thermochemical data.

S + O₂ → SO₂: ΔH = −298.2 kJ

SO₂ + ½ O₂ → SO₃: ΔH = −98.2 kJ

SO₃ + H₂O → H₂SO₄: ΔH = −130.2 kJ

H₂ + ½ O₂ → H₂O: ΔH = −287.3 kJ

The enthalpy of formation of H₂SO₄ at 298 K will be

Accepted Answer

Adding all the given T.C.E.,$\Delta_{f}H_{H_{2}SO_{4}} = - 813.9	ext{ kJ/mol}$
