HALOGENATION OF PROPANONE
Hint
For the proposed mechanism
Iodine appears as neither a reactant or a product in the reversible step. Therefore, the overall rate of iodine consumption will equal the rate of iodine consumption in the iodination step:Overall Rate of Consumption of Iodine {-d[I2]/dt}
For the proposed mechanism
The overall rate of consumption of iodine can be expressed as
