  1. Question 1

    Q1. For a multi-step reversible reaction, how is the equilibrium constant Kc related to the rate constants of the forward and reverse elementary steps?

    • A) The sum of the rates of all elementary steps
    • B) The product of the rate constants of all steps
    • C) The ratio of the forward and backward rate constants
    • D) The rate of the slowest step only

    Answer: The ratio of the forward and backward rate constants

    Explanation: Kc is the ratio of rate constants of elementary steps (kf/kr). Option D is wrong because Kc is independent of the path.
