Answer : The expression for acid dissociation constant will be:

K_a=([H^+][H_2BO_3^-])/([H_3BO_3])

Explanation :

Acid dissociation constant : It is an equilibrium constant that refers to the dissociation or ionization of an acid.

It is denoted as
K_a .

The given equilibrium reaction is:

$H_3BO_3(aq)\rightleftharpoons H^+(aq)+H_2BO_3^-(aq)$

The expression for acid dissociation constant will be:

K_a=([H^+][H_2BO_3^-])/([H_3BO_3])
