Answer:

Keq=\frac{[O_{2}]^{3} }{[H_{2}O]^{2} }

Explanation:

The equilibrium constant (Keq) is equal to <em>the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients</em>. In Keq we include gases and aqueous species, but not solids nor pure liquids because their concentration remains almost constant over time.

Let's consider the following reaction.

4 KO₂(s) + 2 H₂O(g) ⇄ 4 KOH(s) + 3 O₂(g)

Then, the equilibrium constant is:

Keq=\frac{[O_{2}]^{3} }{[H_{2}O]^{2} }
