AP Chemistry / Unit 7: Equilibrium

7.10 Reaction Quotient and Le Châtelier's Principle

3 practice questions

Notes

Compare $Q$ with $K$:

  • $Q<K$: shift right (forward).
  • $Q>K$: shift left (reverse).
  • $Q=K$: at equilibrium.
  • Only temperature changes $K$.

Practice

$Q=0.5$ and $K=2$. The reaction shifts:
Which changes the value of $K$?
$Q>K$ means there's too much:
