MCQ (Single Correct Answer)

-1

For the reaction H⁺ + BrO$$_3^ - $$ + 3Br^$$-$$ $$ \to $$ 5Br₂ + H₂O
which of the following relation correctly represents the consumption and formation of products.

$${{d\left[ {B{r^ - }} \right]} \over {dt}} = - {3 \over 5}{{d\left[ {B{r_2}} \right]} \over {dt}}$$

$${{d\left[ {B{r^ - }} \right]} \over {dt}} = {3 \over 5}{{d\left[ {B{r_2}} \right]} \over {dt}}$$

$${{d\left[ {B{r^ - }} \right]} \over {dt}} = - {5 \over 3}{{d\left[ {B{r_2}} \right]} \over {dt}}$$

$${{d\left[ {B{r^ - }} \right]} \over {dt}} = {5 \over 3}{{d\left[ {B{r_2}} \right]} \over {dt}}$$
