Question

Express the rate of the reaction in terms of the change in concentration of each of the reactants and products. Express the rate of the reaction in terms of the change in concentration of each of the reactants and products. Rate=12Δ[N2O]Δt=−12Δ[N2]Δt=Δ[O2]Δt Rate=Δ[N2O]Δt=12Δ[N2]Δt=−12Δ[O2]Δt Rate=−Δ[N2O]Δt=−12Δ[N2]Δt=12Δ[O2]Δt Rate=−12Δ[N2O]Δt=12Δ[N2]Δt=Δ[O2]Δt

Answer 1

Answer:

Rate = −1/2 Δ[N2O] / Δt = 1/2 Δ[N2]/ Δt = Δ[O2]/Δt

Explanation:

Based on the reaction:

2 N2O(g) → 2 N2(g)+O2(g)

The rate of reaction is the change in concentration per mole of reaction.

In this problem, 2 moles of N₂O are consumed, the rate per mole of reaction is:

Rate = -1/2 Δ[N₂O] / Δt

Negative because this reactant is consumed

In therms of N₂:

Rate = 1/2 Δ[N₂] / Δt

1/2 because 2 moles are produced per mole of reaction

And for O₂:

Rate = Δ[O₂] / Δt

Right solution is:

Rate = −1/2 Δ[N2O] / Δt = 1/2 Δ[N2]/ Δt = Δ[O2]/Δt
