Question

In acidic medium the rate of reaction between $(B r O_{3})^{-}$ and $B r^{-}$ ion is given by the expression.
$- [d (B r O_{3}^{-}) / d t] = K [B r O_{3}^{-}] [B r^{-}] [H^{+}]^{2}$ . It means:

A

Rate constant of overall reaction is

4 s e c^{- 1}

Solution

The correct option is D Doubling the concentration of $H^{+}$ ions will increase the reaction rate by 4 times.
Based on the given rate constant

On Doubling the concentration of $H^{+}$ ions will increase the reaction rate by $2^{2} t i m e s$ = 4 times
