Question

Which of the following expressions is correct for the rate of reaction given below?
$5Br^-(aq) + BrO_3^-(aq) + 6H^+(aq) \rightarrow 3Br_2(aq) + 3H_2O(t)$
(a) $\frac{\Delta [Br^-]}{\Delta t} = 5 \frac{\Delta [H^+]}{\Delta t}$
(b) $\frac{\Delta [Br^-]}{\Delta t} = \frac{6}{5} \frac{\Delta [H^+]}{\Delta t}$
(c) $\frac{\Delta [Br^-]}{\Delta t} = \frac{5}{6} \frac{\Delta [H^+]}{\Delta t}$
(d) $\frac{\Delta [Br^-]}{\Delta t} = 6 \frac{\Delta [H^+]}{\Delta t}$

Answer 1

b part is the correct answer
