  1. Question 1

    Q1. The unit of rate constant for a third-order reaction is

    • A) L² mol^-2 s^-1
    • B) L mol^-1 s^-1
    • C) mol L^-1 s^-1
    • D) s^-1

    Answer: L² mol^-2 s^-1

    Explanation: For third-order, rate = k[A]³, so k has units of L² mol^-2 s^-1, derived from rate / [A]³.
