In acidic medium the rate of reaction between BrO3- and Br- ions is given by the expression:
-\(\frac{d(BrO_3^-)}{dt}\) = k[BrO3-][Br-][H+]2
Which of the following is indicated by the above expression?
Answer & explanation
Correct answer: option 4
As rate of reaction is given by = -\(\frac{d(BrO_3^-)}{dt}\) = k[BrO3-][Br-][H+]2
it shows that rate of reaction is of 2nd order with respect to H+.
Hence, Doubling the concentration of H+ ions will increase the reaction rate by 4 times.
