The iodide ion reacts with hypochlorite ion (the active ingredient in chlorine bleaches) in the following way:

OCl−+I−→OI−+Cl−.

This rapid reaction gives the following rate data:

[OCl−](M) [I]−(M) Rate (M/s)
1.5×10^−3 1.5×10^−3 1.36×10^−4
3.0×10^−3 1.5×10^−3 2.72×10^−4
1.5×10^−3 3.0×10^−3 2.72×10^−4

a. Write the rate law for this reaction.
b. Calculate the rate constant with proper units.
c. Calculate the rate when [OCl-]= 1.8×10^3 M and [I-]= 6.0×10^4 M .

a) The rate law for this reaction:

b)The rate constant of the reaction is .

c)The rate of the reaction at given concentration will be .
