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.
Initial concentrations, M
| [CH3COCH3] | [Br2] | [H+] |
| 0.30 | 0.05 | 0.05 |
| 0.30 | 0.10 | 0.05 |
| 0.30 | 0.10 | 0.10 |
| 0.40 | 0.05 | 0.20 |
Initial rate, disappearance of Br2, Ms-1
5.7 × 10-5
5.7 × 10-5
1.2 × 10-4
3.1 × 10-4
Based on these data, the rate equation is:
- Rate = k [CH3COCH3] [H+]
- Rate = k [CH=COCH3] [Br2]
- Rate = k [CH3COCH3] [Br2] [H+]2
- Rate = k [CH3COCH3] [Br2] [H+]
Answer
(D) Rate = k [CH 3 COCH 3 ] [Br 2 ] [H + ]
