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.
