## Abstract The fast flow method with laser induced fluorescence detection of CH~3~C(O)CH~2~ was employed to obtain the rate constant of __k__~1~ (298 K) = (1.83 ± 0.12 (1σ)) × 10^10^ cm^3^ mol^−1^ s^−1^ for the reaction CH~3~C(O)CH~2~ + HBr ↔ CH~3~C(O)CH~3~ + Br (1, −1). The observed reduced react
