Question

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 1

a.

`K=([BaO]^2)/([Ba]^2[O_2])`

b.

`K=([MgO]^2)/([Mg]^2[O_2])`

c.

`K=([P_4O_(10)]^2)/([P_4][O_2]^5)`

Step-by-step 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.

`K=([BaO]^2)/([Ba]^2[O_2])`

b. 2 Mg + O2 ⇌ 2MgO

`K=([MgO]^2)/([Mg]^2[O_2])`

c. P4 + 5 O2 ⇌ P4O10

`K=([P_4O_(10)]^2)/([P_4][O_2]^5)`
