3.1.6.2. equilibrium constant (Kc)

• what does Kc indicate for reversible reactions?

  the position of equilibrium for a reaction at a certain temperature
• what happens to the Kc value for a reaction?


  it always has the same value unless the reaction conditions and position of equilibrium is changed
• what needs to be known to find the Kc?

  the concentrations of the substances in the reaction at the equilibrium position
• Kc equation

  
• what do the units of the equilibrium constant depend on?

  the chemical reaction
• how can the units be calculated?

  by subbing the units into the Kc expression
• what is the Kc value not affected by?

  concentration change or the use of a catalyst
• what is the ONLY thing Kc is affected by?

  changing the reaction temperature - equilibrium position changes results in different concentrations of reactants and products
• Kc units
