For a reaction aA $\rightarrow$products, [A] 0 = 4.0 M, and the first three successive half-lives are 48, 96, and 192 min.
-Calculate k (without units).

Question

Quizplus · Accepted Answer

The correct answer is A because the rate constant (k) can be calculated using the formula k = (ln 2) / t1/2, where t1/2 is the half-life. The first half-life is 48 min, so k = (ln 2) / 48 = 5.2 x 10^-3 min^-1.
