Question

Using the equation 4HCl + O₂ ↔ 2Cl₂ + 2H₂O + 20 kJ, if O₂ is added, in which direction does the equilibrium shift?

A) To the right
B) To the left
C) No shift in equilibrium
D) Uncertain shift

Answer 1

If O₂ is added, the equilibrium will shift to the right (Option A).

Step-by-step explanation:

The equation provided is 4HCl + O₂ ↔ 2Cl₂ + 2H₂O + 20 kJ. If O₂ is added, the equilibrium will shift to the right (Option A). Adding O₂ to the reaction will increase the concentration of O₂, leading to an increase in the concentration of the products (Cl₂ and H₂O) to reach a new equilibrium.
