    In the reaction.\[Br{{O}^{-}}_{3}(aq)+5B{{r}^{-}}(aq)+6{{H}^{+}}\to 3B{{r}_{2}}(l)+3{{H}_{2}}O(l)\] The rate of appearance of bromine \[(B{{r}_{2}})\]Is related to rate of disappearance .of bromide ions as following:                    

    A) \[\frac{d(B{{r}_{2}})}{dt}=\frac{3}{5}\frac{d(B{{r}^{-}})}{dt}\]         

    B)  \[\frac{d(B{{r}_{2}})}{dt}=-\frac{3}{5}\frac{d(B{{r}^{-}})}{dt}\]

    C) \[\frac{d(B{{r}_{2}})}{dt}=-\frac{5}{3}\frac{d(B{{r}^{-}})}{dt}\]        

    D) \[\frac{d(B{{r}_{2}})}{dt}=\frac{5}{3}\frac{d(B{{r}^{-}})}{dt}\]

    Correct Answer: B

    Solution :

    \[\frac{1}{3}\frac{d[B{{r}_{2}}]}{dt}=-\frac{1}{5}\frac{d[B{{r}^{-}}]}{dt}=R\]
