The bromination of acetone is catalyzed by acid.

The rate of disappearance of bromine was measured for several different initial concentrations of acetone, bromine, and hydronium ion.

(a) Deduce the rate law for the reaction and give the order with respect to each reactant.

(b) What is the numerical value of k, the rate constant?

(c) If [H₃O⁺] is maintained at 0.050 M, whereas both [CH₃COCH₃] and [Br₂] are 0.10 M, what is the rate of the reaction?
