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]

Thus, the rate of consumption of ozone would be written,

-d[O₃]/dt = k[O₃][NO]

and the rate of production of ozone would be written,

+d[O₃]/dt = -k[O₃][NO]

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

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]
