DECOMPOSITION OF AZOMETHANE

Review

Overall Reaction	AZO → C2H6 + N2
Experimental Rate Law (at low [AZO])	+d[N2]/dt = ka[AZO]2
Proposed Mechanism
Rate of Production of (Azomethane)* in the 1st Elementary Step	(d[AZO*]/dt)1 = k1[AZO]2
Rate of Production of (Azomethane)* in the 2nd Elementary Step	(d[AZO*]/dt)2 = -k-1[AZO][AZO*]

Rate of Production of (Azomethane)* in the Third Elementary Step {(+d[AZO*]/dt)₃}

And for the third elementary step,

+d[AZO*]/dt = -k₂[AZO*]

+d[AZO*]/dt = +k₂[AZO*]

+d[AZO*]/dt = -k₂[C₂H₆)][N₂]

+d[AZO*]/dt = +k₂[C₂H₆)][N₂]
