  1. Question 1

    Q1. For a second-order reaction, the rate constant is 0.01 M-1s-1. If the initial concentration is 1 M, what is the half-life?

    • A) 100 s
    • B) 50 s
    • C) 200 s
    • D) 150 s

    Answer: 100 s

    Explanation: For a second-order reaction, t1/2 = 1 / (k[A]0) = 1 / (0.01*1) = 100 s.
