Which way does the equilibrium shift?
Tap a card, then tap its group.
Assumptions
•
The reaction is N₂ + 3H₂ ⇌ 2NH₃, and the forward reaction gives off heat (ΔH < 0).
•
A system at equilibrium shifts to undo a change (Le Châtelier’s principle).
•
Squeezing favors the side with fewer gas molecules: 2 on the right, 4 on the left.
