  1. Question 1

    Q1. The rate law for the reaction A + B -> C is rate = k[A][B]. If [A] = [B] = 0.1 M, the rate is 0.01 M/s. What is the rate constant?

    • A) 1 M^-1s^-1
    • B) 0.1 M^-1s^-1
    • C) 10 M^-1s^-1
    • D) 0.01 M^-1s^-1

    Answer: 1 M^-1s^-1

    Explanation: k = rate / ([A][B]) = 0.01 / (0.1 x 0.1).
