Use these 3 free Unit 14 practice problems as your starting point. When you want more reps on K, Q, Le Chatelier, and equilibrium shifts, premium unlocks Quick Sets of 3, Standard Sets of 9, and Extended Sets of 18 from this 81-problem bank.
3 Free Sample Problems
Work these 3 to find out whether the equilibrium logic is clear enough to follow step by step — or whether the reasoning still needs more practice before it holds up on a test.
#4Reaction Quotient Q
For N2 + 3 H2 ⇌ 2 NH3, K = 0.500. If [N2] = 0.200 M, [H2] = 0.300 M, [NH3] = 0.100 M, calculate Q and predict which direction the reaction proceeds.
#5Le Chatelier's Principle
For the equilibrium N2(g) + 3H2(g) ⇌ 2NH3(g), ΔH = -92 kJ. Increasing the temperature will…
#6Full ICE Table
For CO(g) + H2O(g) ⇌ CO2(g) + H2(g), K = 1.60. Start: [CO]0 = 0.500 M, [H2O]0 = 0.400 M. Find [CO2] at equilibrium.
Prep for the test — not just the homework
The 3 free problems show you where you stand. The full bank is how you close the gaps before the test.
Randomized every time — fresh problems that force real understanding, not answer memorization
Full worked solutions — see exactly where your setup went off track, not just whether you were right
81 problems across equilibrium expressions, Q vs K, ICE tables, and Le Châtelier's Principle
Quick (3), Standard (9), or Extended (18) — use whatever fits your schedule
Filter by type — focus on calculation, concept, or multi-step problems first
