Question

c + 2h₂ ⇌ ch₄
if some ch₄ is removed, which direction will the equilibrium shift to reestablish the balance?
the equilibrium will shift to the left, forming more c and h₂.
the equilibrium will shift to the right, forming more ch₄.
the equilibrium will shift randomly without a predictable direction.
the equilibrium will remain unchanged.

Explanation:

To determine the equilibrium shift, we use Le Chatelier's principle, which states that if a stress is applied to a system at equilibrium, the system will shift in a direction to counteract that stress. In the reaction \( \text{C} + 2\text{H}_2
ightleftharpoons \text{CH}_4 \), removing \( \text{CH}_4 \) (the product) is a stress. The system will try to counteract this by producing more \( \text{CH}_4 \), so the equilibrium shifts to the right (towards the product side) to re - establish balance.

Answer:

The equilibrium will shift to the right, forming more \( \text{CH}_4 \).
