Chemistry equilibrium practice questions
Original equilibrium and Le Chatelier practice with conceptual and calculation focus.
Equilibrium thinking
Do not just say “shifts left” or “shifts right”. Explain the disturbance, the system response and the effect on concentrations/yield.
Explain the effect of increasing pressure on the equilibrium yield of a gaseous reaction where the products side has fewer moles of gas.
A manufacturer changes temperature to increase product yield but reaction rate decreases. Evaluate the trade-off involved.
Describe how a catalyst affects the rate at which equilibrium is reached and whether it changes the equilibrium position.
Common trap
A catalyst changes rate, not equilibrium yield. Temperature can change equilibrium position; pressure only matters for gases with different mole numbers.
