A reaction is first order in A.If the rate constant of the reaction is 3.45 * 10^-3 s^-1, what is the half-life (t_1/2) of the reaction?

Question

Quizplus · Accepted Answer

For a first-order reaction, the half-life (t1/2) is given by the formula t1/2 = 0.693/k, where k is the rate constant. Given k = 3.45 x 10^-3 s^-1, substituting into the formula gives t1/2 = 0.693 / (3.45 x 10^-3 s^-1) = 200.87 s, which rounds to 201 s.
