  1. Question 1

    Q1. For the reaction N2O4 ⇌ 2NO2, if the degree of dissociation is α, what is the expression for Kp?

    • A) 4α²P / (1 - α²)
    • B) α²P / (1 - α)
    • C) 4α²P / (1 + α)
    • D) αP / (1 - α)

    Answer: 4α²P / (1 - α²)

    Explanation: Kp = (partial pressures of products) / (partial pressures of reactants); for N2O4 ⇌ 2NO2, Kp = (4α²P) / (1 - α²).
