Problem: Dinitrogen monoxide decomposes into nitrogen and oxygen when heated. The initial rate of the reaction is 2.4 × 10−2 M/s. What is the initial rate of change of the concentration of N2O (that is, Δ[N2O]/Δt)?2 N2O(g) → 2 N2(g) + O2(g)

Recall that for a reaction aA  bB, the rate of a reaction is given by:

Rate=-1aΔ[A]Δt=1bΔ[B]Δt


We can simply do a rate-to-rate comparison based on the stoichiometric coefficients.

Reaction: dinitrogen monoxide → nitrogen and oxygen

Reaction: 2 N2O(g) → 2 N2(g) + O2(g)


Given:

rate=2.4×10-2 Ms


Since N2O is a reactant, the rate should be negative since reactants are used up/consumed
