The first-order reaction,2 N₂O(g)→ 2 N₂(g)+ O₂(g),has a rate constant equal to 0.76 s^-1 at 1000 K.How long will it take for the concentration of N₂O to decrease to 12% of its initial concentration?

Question

Quizplus · Accepted Answer

For a first-order reaction, the time to reach a certain concentration is given by the formula t = (1/k) * ln([A]₀/[A]). Here, [A]₀/[A] = 1/0.12, k = 0.76 s⁻¹. Plugging in the values, t = (1/0.76) * ln(1/0.12) ≈ 2.8 s.
