DECOMPOSITION OF AZOMETHANE

Hint

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

Example:

For the elementary reaction, O₃ + NO → NO₂ + O₂

r = -d[O₃]/dt = -d[NO]/dt = +d[NO₂]/dt = + d[O₂]/dt

r = k[O₃]¹[NO]¹ = k[O₃][NO]

Rate of Production of Nitrogen in the Third Elementary Step {+(d[N₂]/dt)₃}

For the third elementary step,

the rate of production of Nitrogen would be

+d[N₂]/dt = -k₂[AZO*]

+d[N₂]/dt = +k₂[AZO*]

+d[N₂]/dt = -k₂[N₂]

+d[N₂]/dt = +k₂[N₂]

+d[N₂]/dt = -k₂[C₂H₆][N₂]

+d[N₂]/dt = +k₂[C₂H₆][N₂]
