Question 56 of 118

In acidic medium the rate of reaction between (BrO3)- and Br- ions is given by the expression

-d(BrO3-)dt=KBrO3-Br-H+2

It means:

(a) rate constant of overall reaction is 4 sec-1

(b) rate of reaction is independant of the concentration of acid

(c) the change in pH of the solution will not affect the rate

(d) doubling the conc. of H+ ions will increase the reaction rate by 4 times
