For a reaction I−+OCl−→IO−+Cl−I^{-} + OCl^{-} \rightarrow IO^{-} + Cl^{-} in an g aqueous medium, the rate of reaction is given by d[IO−]dt=k[I−][OCl−][OH−]\frac{d\lbrack IO^{-}\rbrack}{dt} = k\frac{\lbrack I^{-}\rbrack\lbrack OCl^{-}\rbrack}{\lbrack OH^{-}\rbrack}. The overall order of reaction is

A

-1

B

0

C

1

D

2

Answer

1

Explanation

Solution

d[IO−]dt=k[I−]1[OCl−]1[OH−]1\frac{d\lbrack IO^{-}\rbrack}{dt} = k\frac{\lbrack I^{-}\rbrack^{1}\lbrack OCl^{-}\rbrack^{1}}{\lbrack OH^{-}\rbrack^{1}}

Order of reaction = 1+1-1=1
