  1. Question 1

    Q1. What is the expression for Kc for the reaction 2NO2 ⇌ N2O4?

    • A) [N2O4] / [NO2]
    • B) [N2O4] / [NO2]²
    • C) [NO2]² / [N2O4]
    • D) [NO2] / [N2O4]

    Answer: [N2O4] / [NO2]²

    Explanation: Kc = [products] / [reactants] raised to their stoichiometric coefficients, so Kc = [N2O4] / [NO2]².
