JEE Main 2026 Chemistry question

Observe the following reactions at T(K) I. A → products. II. 5Br-(aq)+BrO3-(aq)+6H+(aq) → 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-]/Δt 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?

• 210-3
• 310-2
• 44 × 10-3Correct
