Essential Chemistry for IGCSE - Chemical Reactions (Section 4 - No. 5)
In the reaction: 2H₂(g) + O₂(g) ⇌ 2H₂O(g) , what is the effect of decreasing the volume of the container?
The equilibrium shifts to the left.
The equilibrium shifts to the right.
The equilibrium remains unchanged.
The reaction stops.
Explanation
Decreasing the volume favors the side with fewer moles of gas; thus the equilibrium shifts to the right.
