A first- order reaction has a rate constant of 0.33 min^-¹. It takes min for the reactant concentration to decrease from 0.13 M to 0.088 M.

Question

Quizplus · Accepted Answer

For a first-order reaction, the time taken for the concentration to decrease can be calculated using the formula: t = (1/k) * ln([A]₀/[A]). Substituting the given values, t = (1/0.33) * ln(0.13/0.088) ≈ 1.2 minutes.
