  1. Question 1

    Q1. For the reaction 2SO3 ⇌ 2SO2 + O2, if the degree of dissociation is α, what is the equilibrium constant Kp?

    • A) α³P² / (1 - α²)
    • B) α³P² / (1 - α)²
    • C) α³P / (1 - α)²(2+α)
    • D) α²P / (1 - α)

    Answer: α³P / (1 - α)²(2+α)

    Explanation: Kp = (α/(1+α/2)) × (α/(1+α/2)) × ((1+α)/(1+α/2))P = α³P / (1 - α)²(2+α)
