I have been set a question about orders of reaction on an experiment I carried out. Although I am a little confused. The question is:
How is the rate of reaction of bromine with the ketone apparent in an observable sense in the first stage of this preparation? What order of reaction would you ascribe to the bromination of acetophenone?

The Ketone being acetophenone
Thanks in advance
Observable in the sense that brown colouration of the solution should gradually disappear.
Ist step in the bromonation will be the enolisation which should be second order (1st order for both the acetophenone and base) as it requires deprotonation of the acetophenone with a base.

I had to look up what enolisation was. So I would have first added a base before the bromine? To form the enol from the ketone?
