The gas phase decomposition 2N2O54NO2+O2 has been found to follow the mechanism N2O5NO2+NO3NO2+NO3NO2+NO+O2NO3+NO2NO2 Experimental measurements lead to the following rate law expression rN205=kexpCN205 If NO and NO3 are considered to be active intermediates, please derive the relationship between the experimentally observed rate constant, kexp, and the rate constants for the elementary steps using pseudo steady state hypothesis
