Explanation / Answer

NH3(aq)+ HBrO(aq) <--> NH+4 (aq) + BrO- (aq) Kn= {[NH4+]*[ BrO-]}/{[NH3]*[HBrO]}

(A) NH3 + H2O < ---> NH4+(aq) + OH-(aq) Kb = {[NH4+]*[OH-]}/{NH3] = 5.8 x 10-10

(B)  HBrO(aq) <--> H+ + BrO- Ka = [H+ ] [BrO- ] / [HBrO] = 2x10-9

Kn = Ka*Kb / Kw

= ( 2x10-9 x 5.8 x 10-10 )/ 1x10-14

= 1.16 x 10-5
