    Missing question:

    Chemical reaction: H₂ + 2ICl → 2HCl + I ₂.

    t₁ = 5 s.

    t₂ = 15 s.

    c₁ = 1,11 M = 1,11 mol/L.

    c₂ = 1,83 mol/L.

    rate of formation = Δc : Δt.

    rate of formation = (c₂ - c₁) : (t₂ - t₁).

    rate of formation = (1,83 mol/L - 1,11 mol/L) : (15 s - 5 s).

    rate of formation = 0,72 mol/L : 10 s.

    rate of formation = 0,072 mol/L·s.
