The standard enthalpy change for the reaction of so3(g) with h2o(l) to yield h2so4(aq) is δh∘ = -227.8 kj . use the following information s(s)+o2(g)→so2(g), δh∘ = -296.8kj so2(g)+12o2(g)→so3(g) , δh∘ = -98.9kj to calculate δh∘f for h2so4(aq) (in kilojoules per mole). [for h2o(l),δh∘f = -285.8kj/mol].
