Answer:

[Cl2O5] = 1.60 M

Explanation:

  • 2Cl2O5(g) → 2Cl2(g) + 5O2(g)

at T ⇒ r = (17.4/M.s)*[Cl2O5]²

1) [Cl2O5] = 1.46 M

⇒ t = 0.400 s ⇒ [Cl2O5] = ?

rate law gnral:

  • - ra = K(Ca)∧α = - δCa/δt

∴ K = 17.4 /M.s

∴ α = 2

⇒ - ∫δCa/Ca² = K∫δt

⇒ [ 1/Ca - 1/Cao ] = K*t

⇒ 1/Ca = K*t + 1/Cao

⇒ Ca = 1/K*t + Cao = [Cl2O5]

∴ Cao = 1.46 M

∴ t = 0.400 s

⇒ [Cl2O5] = 1/[(17.4/M.s)*(0.400s)] + 1.46 M

⇒ [Cl2O5] = 0.1436 M + 1.46 M

⇒ [Cl2O5] = 1.604 M
