Write the equilibrium expressions for each of the following equilibria:
a. 2 Ba + O2 ⇌ 2 BaO
b. 2 Mg + O2 ⇌ 2MgO
c. P4 + 5 O2 ⇌ P4O10

Answer:

a.

[tex]K=\frac{[BaO]^2}{[Ba]^2[O_2]}[/tex]

b.

[tex]K=\frac{[MgO]^2}{[Mg]^2[O_2]}[/tex]

c.

[tex]K=\frac{[P_4O_{10}]^2}{[P_4][O_2]^5}[/tex]

Explanation:

Hello!

In this case, since the equilibrium expression is set up by dividing the products over the reactants and powering to the stoichiometric coefficient, we can proceed as follows:

a. 2 Ba + O2 ⇌ 2 BaO.

[tex]K=\frac{[BaO]^2}{[Ba]^2[O_2]}[/tex]

b. 2 Mg + O2 ⇌ 2MgO

[tex]K=\frac{[MgO]^2}{[Mg]^2[O_2]}[/tex]

c. P4 + 5 O2 ⇌ P4O10

[tex]K=\frac{[P_4O_{10}]^2}{[P_4][O_2]^5}[/tex]
