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.
