Problem 3 [0.5 pt] The gas phase decomposition 2N203 + 4NO2 + O2 has been found to follow the mechanism N205 H NO2 + NO3 NO2 + NO3 + NO2 + NO + O2 NO3 + NO + 2N02 Experimental measurements lead to the following rate law expression -"N205 = kexpC 2205 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
