Kc

• what is Kc 


  equilibrium constant
• if Kc is 1 then the position of equilibrium is halfway between reactants and products
• if Kc is less than 1 then the position of equilibrium is towards the reactants
• if Kc is more than 1 then the position of equilibrium is towards the products
• Kc = [Products] / [reactants]
• changes in concentration or pressure don't affect K as its a constant
• if K values drop when temperature is increased it tells us the forward reaction is exothermic
