QUESTION #61 First Order Reactions
Observe the following reactions at T(K) I. A rightarrow textproducts. II. 5Br^-(aq) + BrO_3^-(aq) + 6H^+(aq) rightarrow 3Br_2(aq) + 3H_2O(l) Both the reactions are started at 10.00 am. The rates of these reactions at 10.10 am are same. The value of -fracDelta[Br^-]Delta t at 10.10 am is 2 times 10^-4 text mol L^-1 text min^-1. The concentration of A at 10.10 am is 10^-2 text mol L^-1. What is the first order rate constant (in textmin^-1) of reaction I?
