The Knet for this reaction would have the form [benzoate ion][hypochlorous acid]/[benzoic acid][hypochlorite ion].
Ka for benzoic acid equals [benzoate ion][hydrogen ion]/[benzoic acid].
Kb for hypochlorite ion equals [hypochlorous acid]/[hydrogen ion][hypochlorite ion] or 1/Ka for hypochlorous acid.
Multiplying Ka by Kb expressions left side by left side and right side by right side eliminates the hydrogen ion concentration and results in the Knet expression above, whose numerical value is then the Ka value for benzoic acid divided by the Ka value for hypochlorous acid.

I want the values. You'll need a table of ionization constants to solve it. I try to post it but my comment gets put under review.05/04/22
