Asked by admin @ in Chemistry viewed by 316 People
The bromination of acetone that occurs in acid solution is
represented by this equation.
CH₃COCH₃ (aq) + Br₂ (aq) → CH₃COCH₂Br (aq) + H⁺
(aq) + Br⁻ (aq)
These kinetic data were obtained for given reaction
concentrations.

Based on given data, the rate equations is:
(a) Rate = k[CH₃COCH₃][H⁺]
(b) Rate = k [CH₃COCH₃][Br₂]
(c) Rate = k [CH₃COCH₃] [Br₂] [H⁺]²
(d) Rate = k [CH₃COCH₃][Br₂] [H⁺]
