For which of the following reactions is ΔH rxn equal to ΔHf of the product(s)?

You do not need to look up any values to answer this question. Check all that apply.

i) SO(g) + ½O2(g) → SO2(g)

ii) 2Na(s) + F2(g) → 2NaF(s)

iii) Na(s) + ½F2(g) → NaF(s)

iv) S(s) + O2(g) → SO2(g)

v) Na(s) + ½F2(l) → NaF(s)

vi) SO3(g) → ½O2(g) + SO2(g)
