# NEET Chemistry Chemical Kinetics Questions Solved

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

$-\frac{d\left({\mathrm{BrO}}_{3}^{-}\right)}{dt}=K\left[{\mathrm{BrO}}_{3}^{-}\right]\left[{\mathrm{Br}}^{-}\right]{\left[{\mathrm{H}}^{+}\right]}^{2}$

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
