EQUILIBRIUM

At Equilibrium: 
• the amounts of reactants /
  products do not change with time.
• rate of forward & back reaction are equal
Kc     =             [product C]c          
                 [reactant A]a [reactant B]b
•  a, b, c are from the balanced equation
• Kc is the equilibrium constant which tells
  us the extent of reaction at completion.
