What is the reaction the following general rates describe?

Question

Rate =2(Δ[O2]/Δt) = 1/2(Δ[NO2]/Δt) = -(Δ[N2O5]/Δt)

4 NO2 + O2 → 2 N2O5

2 NO2 + 1/2 O2 + N2O5 → products

2 NO2 + 1/2 O2 → N2O5

N2O5 → 2 NO2 + 1/2 O2

2 N2O5 → 4 NO2 + O2

Answer 1

The given general rates describe the reaction:

2 NO2 + 1/2 O2 → N2O5
