    Equilibria
    Write the balanced equation for the synthesis of Ammonia
    Include Kc expression
    Include energy level diagram
    http://www.youtube.com/watch?v=uAJDD1_Oexo
+
    Aims

       Introduce dynamic equilibria for both chemical and physical
        change.



       Game 

+
+
    Definition 2

       Physical Dynamic Equilibria.



       i.e. water
+
    Definition 3

       The ‘closed system’….



       A closed system is one in which no substances are either
        aeddd to the system or lost from it. Energy
        can, however, beeerrransftdin or out at will.
+
    Summary

       A dynamic equilibrium occurs when you have a verreslebi
        reaction in a closed system. Nothing can be dddae to the
        system or taken away from it apart fromregnye.



       At equilibrium, the quantities of everything nresept in the
        mixture remain constant, although the reactions are
        stilluinitconng. This is because the rates of the forward and the
        back reactions arealeuq.

    The Equilibrium Constant

       This is derived from concentrations – can be gases or liquids.



       NB Always [products] / [reactants]



       NB2 – this is for homogeneous reactions
+
    Magnitude of Kc

       Kc is constant at constant T.



       Changing Pressure or concentration or adding a catalyst do not
        change Kc.



       If Kc>>1 – rxn goes to completion.

       If Kc<<1 – rxn hardly proceeds.

       If Kc 10-2 – 102 then [reactants] and [products] are present in the
        equilibirum mixture.
+
    Your Task

       Who was Le Chatelier ?

       What did he find out about equilibria ?

       Discuss effect on Haber ( F ) or Contact ( M ) processes of altering the
        following ..
           Temperature
           Pressure
           Concentration
           Catalyst

       MUST be communicated in an entertaining manner !

    Key Concepts in Equilibria
    Equilibrium    reactions are reversible chemical reactions.

    rate   of the forward reaction = the rate of the reverse
        reaction

    At   equilibrium the concentration of reactants / products
        does not change with time.

       Catalysts do not affect the position of equilibrium

        Heat increases the rate of both the forward and reverse
        reaction.

    Only    closed systems can reach equilibrium.
+
    Le Chatelier’s Principle

       When a system at equilibrium is disturbed, the equilibrium
        position will shift in the direction which tends to minimise, or
        counteract, the effect of the disturbance.
+
    Disturbances on Equilibrium

    * If the concentration of a solute reactant is increased, the equilibrium position
       shifts to use up the added reactants by producing more products.



      * If the pressure on an equilibrium system is increased, then the equilibrium
      position shifts to reduce the pressure.



      * If the temperature of an endothermic equilibrium system is increased, the
      equilibrium position shifts to use up the heat by producing more products.



      * If the temperature of an exothermic equilibrium system is increased, the
      equilibrium position shifts to use up the heat by producing more reactants.
+
    Effect of Catalyst

       A catalyst speeds up the rate of both the forward and reverse
        reactions.

       The initial slope of the concentration vs time lines will be
        steeper for both reactants and products.



       A catalyst does NOT affect the equilibrium position.

       At equilibrium the concentrations of reactants and products for
        the catalysed reaction are the same as for the uncatalysed
        reaction.

G11 s lequilibria

  • 1. + Equilibria Write the balanced equation for the synthesis of Ammonia Include Kc expression Include energy level diagram http://www.youtube.com/watch?v=uAJDD1_Oexo
  • 2. + Aims  Introduce dynamic equilibria for both chemical and physical change.  Game 
  • 3. + Definition 1 Chemical Equilibria http://www.youtube.com/watch?v=tlGrBcgA NSY&feature=related
  • 4. +
  • 5. + Definition 2  Physical Dynamic Equilibria.  i.e. water
  • 6. + Definition 3  The ‘closed system’….  A closed system is one in which no substances are either aeddd to the system or lost from it. Energy can, however, beeerrransftdin or out at will.
  • 7. + Summary  A dynamic equilibrium occurs when you have a verreslebi reaction in a closed system. Nothing can be dddae to the system or taken away from it apart fromregnye.  At equilibrium, the quantities of everything nresept in the mixture remain constant, although the reactions are stilluinitconng. This is because the rates of the forward and the back reactions arealeuq.
  • 8. + Chemical Equilibria  http://www.youtube.com/watch?v=0XQVXFL4uoo  http://www.youtube.com/watch?v=GS9kIj9n- BU&feature=related
  • 9. + The Equilibrium Constant  This is derived from concentrations – can be gases or liquids.  NB Always [products] / [reactants]  NB2 – this is for homogeneous reactions
  • 10. + Magnitude of Kc  Kc is constant at constant T.  Changing Pressure or concentration or adding a catalyst do not change Kc.  If Kc>>1 – rxn goes to completion.  If Kc<<1 – rxn hardly proceeds.  If Kc 10-2 – 102 then [reactants] and [products] are present in the equilibirum mixture.
  • 11. + Your Task  Who was Le Chatelier ?  What did he find out about equilibria ?  Discuss effect on Haber ( F ) or Contact ( M ) processes of altering the following ..  Temperature  Pressure  Concentration  Catalyst  MUST be communicated in an entertaining manner !  http://www.chem1.com/acad/webtext/chemeq/Eq-02.html#SEC1
  • 12. + Key Concepts in Equilibria Equilibrium reactions are reversible chemical reactions. rate of the forward reaction = the rate of the reverse reaction At equilibrium the concentration of reactants / products does not change with time.  Catalysts do not affect the position of equilibrium  Heat increases the rate of both the forward and reverse reaction. Only closed systems can reach equilibrium.
  • 13. + Le Chatelier’s Principle  When a system at equilibrium is disturbed, the equilibrium position will shift in the direction which tends to minimise, or counteract, the effect of the disturbance.
  • 14. + Disturbances on Equilibrium * If the concentration of a solute reactant is increased, the equilibrium position shifts to use up the added reactants by producing more products. * If the pressure on an equilibrium system is increased, then the equilibrium position shifts to reduce the pressure. * If the temperature of an endothermic equilibrium system is increased, the equilibrium position shifts to use up the heat by producing more products. * If the temperature of an exothermic equilibrium system is increased, the equilibrium position shifts to use up the heat by producing more reactants.
  • 15. + Effect of Catalyst  A catalyst speeds up the rate of both the forward and reverse reactions.  The initial slope of the concentration vs time lines will be steeper for both reactants and products.  A catalyst does NOT affect the equilibrium position.  At equilibrium the concentrations of reactants and products for the catalysed reaction are the same as for the uncatalysed reaction.
