The gas phase decomposition of azomethane to give ethane and nitrogen takes place according to the following sequence of elementary reactions. (CH3)2N2+(CH3)2N2 → k1 (CH3)2N2+[(CH3)2N2]*
[(CH3)2N2]*+(CH3)2N2 → k2 (CH3)2N2+ (CH3)2N2
[(CH3)2N2]* → k3 C2H6+N2
Using the pseudo-steady-state-approximation for [(CH3)2N2]* the order with respect to azomethane in the rate expression for the formation of ethane, in the limit of high concentrations of azomethane, is
