For the second order reaction A → products,the following data are obtained:
[A] = 3.024 M,t = 0 min
[A] = 2.935 M,t = 1.0 min
[A] = 2.852 M,t = 2.0 min
What is the rate constant,k?

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 two time intervals gives k ≈ 1.0 × 10⁻² M⁻¹ min⁻¹.
