To which one of the following reactions occurring at 25°C does the symbol ΔH°f of HNO3(l) refer?

a. H(g) + N(g) + O3(g) → HNO3(l)

b. (1/2)H2(g) + (1/2)N2(g) + (3/2)O2(g) → HNO3(l)

c. HNO3(l ) → (1/2)H2(g) + (1/2)N2(g) + (3/2)O2(g)

d. HNO3(l) → H(g) + N(g) + 3O(g)

e. H2(g) + N2(g) + O3(g) → HNO3(l)
