Answer 1

Answer:

2CO₂ ⇄ 2CO + O₂.

Explanation:

• The equilibrium constant (Keq) for a reaction is the ratio of the concentration of the products to the reactants, each one is raised to each molar coefficient.

So, for Keq = [CO]²[O₂]/[CO₂]²,

It is clear that the products are CO and O₂, while the reactant is CO₂.

So, the reaction for this is:

2CO₂ ⇄ 2CO + O₂.
