Chemical Equilibrium

Cards (10)

  • State Le Chatelier's Principle
    When the equilibrium in a closed system is disturbed, the system will re-instate a new equilibrium by favoring the reaction that will oppose the disturbance.
  • Reversible Reaction
    A reaction is reversible when products can be converted back to reactants and vice versa.
  • Chemical Equilibrium
    It is a dynamic equilibrium when the rate of the forward reaction equals the rate of the reverse reaction.
  • How to Answer Le Chateliers Principle Questions

    1.Identify the change.
    2. Reaction of the system (how will the system counteract the change?)
    3. Favoured reaction.
    4. Effect
  • Kc value only changes with what variable?
    TEMPERATURE
  • Kc < 1 =?
    Reverse reaction favored,
    [Products] < [Reagents]
  • Kc > 1 =?
    Forward reaction favored,
    [products]> [reagents]
  • Open System
    An open system continuously interacts with its environment.
  • Closed system
    Is isolated from its surroundings.
  • Factors that Influence the position of an equilibrium.
    • pressure (gases only)
    • concentration
    • temperature.
