Kinetics of Thermal Decomposition of N2O5

The decomposition of N2O5 is shown as-
2N2O5 → 4NO2 + O2
It involves two molecules of N2O5 and therefore, can not follow 1st order kinetics. The possible mechanism is given below-
Kinetics of Thermal Decomposition of N2O5
NO3 and NO are unstable intermediates. Using steady state approximation we have-
Kinetics of Thermal Decomposition of N2O5
Putting the value of [NO3] and [NO] in the above equation we get-
Kinetics of Thermal Decomposition of N2O5
Where K' = 2K1K3/(K2 + K3)
