Assume that the mechanism for the gas phase reaction, 2 NO + O2 = 2 NO2, consists of the following elementary steps. FYI, NO and NO2 have an unpaired electron on the nitrogen atom. In NO3 an unpaired electron is on one of the oxygen atoms. (1) NO + O2 ↔ NO3 (rate coefficients k1 and k-1) (2) NO3 + NO → 2 NO2 (rate coefficient k2) (i)Complete the following expressions with rates of the elementary steps, derive an expression...
