engineering chemistry MCQ #4904

  1. Question 1

    Q1. The rate of reaction 2A + B -> products is given by rate = k[A][B]. If [A] = [B] = 0.1 M, the rate is 0.01 M/s. The rate constant k is

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

    Answer: 1 M^-1 s^-1

    Explanation: k = rate / ([A][B]) = 0.01 / (0.1 * 0.1) = 1 M^-1 s^-1.
