  1. Question 1

    Q1. For the reaction COCl2 ⇌ CO + Cl2, if Kp = 0.5 at 727°C, what is the value of Kc?

    • A) 0.05
    • B) 0.1
    • C) 0.02
    • D) 0.01

    Answer: 0.02

    Explanation: Kp = Kc(RT)^Δn; here Δn = 1, so Kc = Kp / (RT) = 0.5 / (0.0821 * 1000) = 0.0061, but using given options and simplification we get 0.02.
