Consider the collision-induced dissociation of N2O5(g) via the following mechanism:

The asterisk in the first reaction indicates that the reactant is activated through collision.

Experimentally it is found that the reaction can be either first or second order in N₂O₅(g) depending on the concentration of this species. Derive a rate law expression for this reaction consistent with this observation.
