Average rate = Δ[ N2O5 ] / 2Δt

Because we lose reactants and gain products, we are losing [N2O5], and our equation becomes: 

Average rate = - Δ[ N2O5 ] / 2Δt     

Also, remember that ΔN2O5 ]  and Δt = final - initial, and that whatever the coefficient we have for the reactant, we will put that number on the bottom!
