Is it thermodynamically possible to form bromate (BrO,) from bromide (Br) using hydroxyl radicals (HO) for the following conditions? Also, determine whether it is possible to form bro- mate concentrations in excess of 10 g/L, which is its maximum contaminant level.

[HO.] = 10-11 M Br= 0.3 mg/L BrO3= 10 g/L

Half reactions will be used:

HO+ H+ e HO. Ered = 2.59 V

Br+3H₂0BrO3 + 6H* +6e E_ox= -1.437
