DECOMPOSITION OF AZOMETHANE

Hint

For an elementary reaction of the form, aA + bB → cC

Note: Only the reactant concentrations appear in the rate expression (i.e., [A] and [B] for the reaction given above).

Composite or Elementary?

If the reaction

AZO → C₂H₆ + N₂

+d[N₂]/dt = k[C₂H₆]

+d[N₂]/dt = k[C₂H₆][N₂]

+d[N₂]/dt = k[AZO][C₂H₆][N₂]

+d[N₂]/dt = k[AZO]

+d[N₂]/dt = k[AZO]²
