HALOGENATION OF PROPANONE

Hint

Since the reaction is known to be 0th Order with respect to halogen, the following can be written:

Obtaining the 0th Order Rate Coefficient

Therefore, the 0th Order rate coefficient (and hence the rate) can be obtained from the gradient of a plot of

1/[I₂] versus Time

[I₂] versus Time

ln[I₂] versus Time
