DECOMPOSITION OF AZOMETHANE

Hint

For the low azomethane concentration case, it can be assumed that

k_-1[AZO] << k₂

(which can be simplified further by cancelling terms that appear top and bottom)

Obtaining the Final (Derived) Rate Expression for the Production of Nitrogen {+d[N₂]/dt)}

Thus the expression for the rate of production of Nitrogen can be reduced to

d[N₂]/dt = k₁[AZO]²

d[N₂]/dt = k₂[AZO]

d[N₂]/dt = k₂k₁[AZO] / k_-1

d[N₂]/dt = k₂k₁[AZO]²
