At a given temperature, K = 46.0 for the reaction:
4 HCl (g) + O₂ (g) $\rightarrow$ 2 H₂O (g) + 2 Cl₂ (g)
At equilibrium, [HCl] = 0.150, [O₂] = 0.395, and [H₂O] = 0.625. What is the concentration of [Cl₂] at equilibrium?

Question

At a given temperature, K = 46.0 for the reaction:
4 HCl (g) + O₂ (g)

\rightarrow

2 H₂O (g) + 2 Cl₂ (g)
At equilibrium, [HCl] = 0.150, [O₂] = 0.395, and [H₂O] = 0.625. What is the concentration of [Cl₂] at equilibrium?

Quizplus · Accepted Answer

Using the equilibrium constant expression K = ([H2O]^2[Cl2]^2) / ([HCl]^4[O2]), we can solve for [Cl2]. Substituting the given values and solving for [Cl2] gives approximately 0.153 M.

At a Given Temperature, K = 46 →\rightarrow→ 2 H2O (G) + 2 Cl2 (G) at Equilibrium, [HCl]

At a Given Temperature, K = 46 $\rightarrow$ 2 H₂O (G) + 2 Cl₂ (G)
at Equilibrium, [HCl]
