The Equilibrium Constant

15.2.1 Select the equilibrium expression for the reaction

2CO(g) + O₂(g) ⇄ 2CO₂(g)

(a) $K_c=\frac{2{[{\text{CO}}_{\text{2}}]}^2}{2{[\text{CO}]}^2[{\text{O}}_{\text{2}}]}$

(b) $K_c=\frac{{(2[{\text{CO}}_{\text{2}}])}^2}{{(2[\text{CO}])}^2[{\text{O}}_{\text{2}}]}$

(c) $K_c=\frac{2[{\text{CO}}_{\text{2}}]}{2[\text{CO}][{\text{O}}_{\text{2}}]}$

(d) $K_c=\frac{2{[{\text{CO}}_{\text{2}}]}^2}{{[2\text{CO}]}^2[{\text{O}}_{\text{2}}]}$

(e) $K_c=\frac{{[{\text{CO}}_{\text{2}}]}^2}{{[\text{CO}]}^2[{\text{O}}_{\text{2}}]}$
