FeBr3 is a lewis acid and so acts as a sort of electron sink...

Thanks, but is there not an equation I could write?
I guess (but not strictly true): Br2 + FeBr3 ---> Br+ + FeBr4-

That's what I thought, but like you say that's not true as no ions are formed. Isn't it impossible to write an equation for polarisation, as nothing really reacts?

Indeed, this is why we rely on mechanisms to convey this information :smile:
