For the reaction H+ + BrO3−_3^ -3−​ + 3Br−-− →\to→ 5Br2 + H2O
which of the following relation correctly represents the consumption and formation of products.
  1. A
    d[Br−]dt=−35d[Br2]dt{{d\left[ {B{r^ - }} \right]} \over {dt}} = - {3 \over 5}{{d\left[ {B{r_2}} \right]} \over {dt}}dtd[Br−]​=−53​dtd[Br2​]​
  2. B
    d[Br−]dt=35d[Br2]dt{{d\left[ {B{r^ - }} \right]} \over {dt}} = {3 \over 5}{{d\left[ {B{r_2}} \right]} \over {dt}}dtd[Br−]​=53​dtd[Br2​]​
  3. C
    d[Br−]dt=−53d[Br2]dt{{d\left[ {B{r^ - }} \right]} \over {dt}} = - {5 \over 3}{{d\left[ {B{r_2}} \right]} \over {dt}}dtd[Br−]​=−35​dtd[Br2​]​
  4. D
    d[Br−]dt=53d[Br2]dt{{d\left[ {B{r^ - }} \right]} \over {dt}} = {5 \over 3}{{d\left[ {B{r_2}} \right]} \over {dt}}dtd[Br−]​=35​dtd[Br2​]​

Correct answer: A

- {1 \over 3}$$${{d\left[ {B{r^ - }} \right]} \over {dt}} = + {1 \over 5}{{d\left[ {B{r_2}} \right]} \over {dt}}$$ <br><br> \Rightarrow $ d[Br−]dt=−35d[Br2]dt{{d\left[ {B{r^ - }} \right]} \over {dt}} = - {3 \over 5}{{d\left[ {B{r_2}} \right]} \over {dt}}dtd[Br−]​=−53​dtd[Br2​]​
