  1. Question 1

    Q1. The half-life of a second-order reaction depends on the

    • A) Initial concentration of the reactant
    • B) Rate constant of the reaction
    • C) Both initial concentration and rate constant
    • D) Neither initial concentration nor rate constant

    Answer: Both initial concentration and rate constant

    Explanation: For a second-order reaction, t1/2 = 1/(k[A]0), so it depends on both k and [A]0.
