DECOMPOSITION OF AZOMETHANE

Hint

If a species is neither a reactant or a product in a reaction, then the concentration of that species will not change during that reaction.

The differential d[A]/dt represents the rate of change of concentration of A with respect to time.

Rate of Production of Nitrogen in the First Elementary Step {+(d[N₂]/dt)₁}

Since Nitrogen does not appear as either a reactant or a product in the first elementary step,

its rate of production would be

+d[N₂]/dt = +ive

+d[N₂]/dt = 0

+d[N₂]/dt = -ive
