In acidic medium the rate of reaction between (BrO3)- and Br- ions is given by the expression
(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
(d) Note that reaction is second order in [H+].
