  1. Question 1

    Q1. The rate constant for the reaction A → B is 0.02 s^(-1). If [A] = 0.2 M, what is the initial rate?

    • A) 0.004 M/s
    • B) 0.02 M/s
    • C) 0.01 M/s
    • D) 0.1 M/s

    Answer: 0.004 M/s

    Explanation: Initial rate = k[A] = 0.02 × 0.2 = 0.004 M/s for a first-order reaction.
