The mechanism for the reaction described by the equation

The mechanism for the reaction described by the equation2 N2O5(g) –> O2(g) 4 N2O(g)is suggested to be1. N2O5(g) yields (double arrow k1 on the top and k-1 on the bottom) NO2(g) NO3(g)2. NO2(g) NO3(g) yields (k2 on top) NO2(g) O2(g) NO(g)3. NO(g) N2O5(g) yields k3 on top 3NO2(g)Assuming that [NO3] is governed by steady state conditions derive the rate law for the production of O2(g).rate of reaction=delta[O2]/delta t= ?
