Answer:
[tex]equilibruim constant = \frac{[C] . [D] }{[A] }[/tex]
Explanation:
HCO₃⁻(aq) + H₂O(l) ⇆ H₃O⁺(aq) + CO₃⁻²(aq)
if we rewrite using letters
A(aq) + B(l) ⇆ C(aq) + D(aq)
when in aqueous solution, the concentration of the water is not included in the expression of the equilibrium constant because it is assumed constant.
[tex]equilibruim constant = \frac{[C] . [D] }{[A] }[/tex]
Notice that, all the stoichiometric coefficients are equal to 1.
