QUESTION #61 First Order Reactions
Observe the following reactions at T(K) I. A arrow products. II. 5Br⁻(aq) + BrO₃⁻(aq) + 6H⁺(aq) arrow 3Br₂(aq) + 3H₂O(l) Both the reactions are started at 10.00 am. The rates of these reactions at 10.10 am are same. The value of - Δ[Br⁻]Δ t at 10.10 am is 2 × 10⁻⁴ mol L⁻¹ min⁻¹. The concentration of A at 10.10 am is 10⁻² mol L⁻¹. What is the first order rate constant (in min⁻¹) of reaction I?
