You need to provide #pK_a# for hypobromous acid.

Explanation:

We wish to assess the equilibium:

#KOBr(aq) + H_2O(l) rightleftharpoons HOBr(aq) + HO^(-)(aq)#

#K_b=([HO^-][HOBr])/([""^(-)OBr])#

Without the #K_b# value we are shot birds. You will find #K_a# in the literature, and this we can use to assess #K_b#.
