    Missing question: The decomposition of XY is second order in and has a rate constant of 6.96*10 ⁻³ s⁻¹ at a certain temperature.

    c ₀ = 0,050 M.

    t = 55 s.

    k = 6.96*10⁻³ s⁻¹.

    Integrated second order rate law is: 1/c₁ = 1/c₀ + k·t.

    1/c₁ = 1/0,050 M + 0,0069 s⁻¹ · 55 s.

    1/c₁ = 20,38 1/M.

    c₁ = 0,049 M.
