  1. Question 1

    Q1. The rate law for a reaction is rate = k[A][B]. If [A] = [B] = 0.1 M, and k = 0.05 M^(-1)s^(-1), what is the rate?

    • A) 5 × 10^(-4) M/s
    • B) 5 × 10^(-3) M/s
    • C) 5 × 10^(-2) M/s
    • D) 5 × 10^(-5) M/s

    Answer: 5 × 10^(-4) M/s

    Explanation: Rate = k[A][B] = 0.05 × 0.1 × 0.1 = 5 × 10^(-4) M/s.
