  1. Question 1

    Q1. For the reaction 2NO2 ⇌ N2O4, if the equilibrium constant Kc is 170 at 300K, what is the value of ΔG°?

    • A) -8.314 × 300 × ln(170)
    • B) 8.314 × 300 × ln(170)
    • C) -8.314 × 300 × log(170)
    • D) 8.314 × 300 × log(170)

    Answer: -8.314 × 300 × ln(170)

    Explanation: ΔG° = -RT ln(Kc) = -8.314 × 300 × ln(170)
