  1. Question 1

    Q1. For the reaction A + B -> C, the rate law is rate = k[A][B]. If [A] = [B] = 1 M, the rate is 0.01 M/s. What is k?

    • A) 0.01 M-1s-1
    • B) 0.1 M-1s-1
    • C) 1 M-1s-1
    • D) 0.001 M-1s-1

    Answer: 0.01 M-1s-1

    Explanation: k = rate / ([A][B]) = 0.01 / (1*1) = 0.01 M-1s-1.
