For a certain overall third-order reaction with the general form aA $\to$ products,the initial rate of reaction is 0.42 M·s^-1 when the initial concentration of the reactant is 0.25 M.What is the rate constant for this reaction?

Question

Quizplus · Accepted Answer

For a third-order reaction, the rate law is rate = k[A]^3. Given the rate is 0.42 M·s^-1 and [A] is 0.25 M, solve for k: 0.42 = k(0.25)^3, which gives k = 27 M^-2·s^-1.
