4. The decomposition of SO₂Cl₂ is first order in SO₂Cl₂ and has a rate constant of 1.42 x 104 s-¹ at a certain temperature. a. What is the half-life for this reaction? b. How long will it take for the concentration of SO₂Cl₂ to decrease to 25% of its initial concentration? c. If the initial concentration of SO₂Cl₂ is 1.00 M, how long will it take for the concentration to decrease to 0.78 M? d. If the initial concentration of SO₂Cl₂ is 0.150 M, what is the concentration of SO₂Cl₂ after 2.00 x 10² s?
