Chemical Equilibrium

To understand chemical equilibrium you need to realise that
  1. chemical reactions that are in equilibrium DO NOT go to completion. 
  2. "reactants" and "products" are all present at equilibrium
  3. the "things" that are in equilibrium are the "reactants" and "products" whose concentrations can be changed (that is, substances that exist in solution).
  4. equilibrium is the state in which the rate of the forward reaction (reactants → products) is the same as the reverse reaction (products → reactants
Knowing this, we can then write:
And then
Which at equilibrium, results in an expression for the
Which can be used to:
