Question

Write an equilibrium expression for each chemical equation involving one or more solid or liquid reactants or products.

Answer 1

Answer:

a.

$Keq=\frac{[HCO_3^-][OH^-]}{[CO_3^{2-}]}$

b.

$Keq=[O_2]^3$

c.

$Keq=\frac{[H_3O^+][F^-]}{[HF]}$

d.

$Keq=\frac{[NH_4^+][OH^-]}{[NH_3]}$

Explanation:

Hello there!

In this case, for the attached reactions, it turns out possible for us to write the equilibrium expressions by knowing any liquid or solid would be not-included in the equilibrium expression as shown below, with the general form products/reactants:

a.

$Keq=\frac{[HCO_3^-][OH^-]}{[CO_3^{2-}]}$

b.

$Keq=[O_2]^3$

c.

$Keq=\frac{[H_3O^+][F^-]}{[HF]}$

d.

$Keq=\frac{[NH_4^+][OH^-]}{[NH_3]}$
