-What will be the concentration of A when t = 120 seconds?

Quizplus · Accepted Answer

The concentration of A at t = 120 seconds is 0.047 M. This can be calculated using the integrated rate law for a first-order reaction:ln[A] = -kt + ln[A]0where [A] is the concentration of A at time t, [A]0 is the initial concentration of A, k is the rate constant, and t is time.We are given that [A]0 = 0.20 M, k = 0.005 s^-1, and t = 120 s. Substituting these values into the integrated rate law, we get:ln[A] = -0.005 s^-1 * 120 s + ln(0.20 M)ln[A] = -0.6[A] = e^-0.6 = 0.047 M
