For the second order reaction A → products, the following data are obtained: [A] = 1.512 M, t = 0 min
[A] = 1.490 M, t = 1.0 min
[A] = 1.469 M, t = 2.0 min
What is the rate constant, k, for the reaction?

Question

Quizplus · Accepted Answer

For a second-order reaction, the rate law is 1/[A] = kt + 1/[A]₀. Using the given concentrations and times, calculate k using the formula: k = (1/[A] - 1/[A]₀) / t. Substituting the values for t = 1 min and t = 2 min, you find k ≈ 9.7 × 10⁻³ M⁻¹ min⁻¹.
