Use the following information S(s)+O2(g)→SO2(g)S(s)+O2(g)→SO2(g), ΔH∘ΔH∘ = -296.8kJkJ SO2(g)+12O2(g)→SO3(g)SO2(g)+12O2(g)→SO3(g)

, ΔH∘ΔH∘ = -98.9kJkJ to calculate ΔH∘fΔHf∘ for H2SO4(aq)H2SO4(aq) (in kilojoules per mole). [For H2O(l),ΔH∘fH2O(l),ΔHf∘ = -285.8kJ/molkJ/mol]. Express your answer using four significant figures

Answer: The ∆Hf is -384.7kj/mol

Explanation:

H2O +SO3-----H2SO4

-285.8 +(-98.9------- -384.7kj/mol
