The decomposition of sulfuryl chloride, SO₂Cl₂, is a first-order process with a rate constant of 4.50 × 10-2 s-¹ at 660 K. SO₂Cl2(g) → SO2(g) + CO2(g) The initial concentration of SO₂Cl₂ is 0.607 M. Calculate the concentration of SO₂Cl₂ after 16.3 s. [SO₂Cl₂] = M How many seconds does it take for the concentration of SO₂Cl₂ to drop to 2.43 × 10-3 M? t =
