A mechanistic study of reaction between chloramine and sulfite has been reported (B.S. Yiin, D.M. Walker, and D.W. Margerum, Inorg. Chem., 1987, 26, 3435). Summarize the observed rate law and the proposed mechanism. Accepting the proposed mechanism, why should SO₂(OH)⁻ and HSO₃⁻ display different rates of reaction? Explain why it was not possible to distinguish the reactivity of SO₂(OH)⁻ from that of HSO₃⁻.
