How can I increase the amount of product?
Make more NH3
Where did the atoms needed to make NH3 come from?
Reactant N2 and H2 were used to make NH3
What happens to the concentration of H2 as NH3 is made?
The concentration of H2 goes down

How can I increase the amount of reactant?
Make N2 and H2
Where did the atoms needed to make N2 and H2 come from?
NH3 had to be broken apart to replenish reactants

The principle says that if you have a system in
equilibrium and you do anything to it that messes
up the equilibrium, the system will try to move back
to the original state of equilibrium. Or, if you have a
happy system and you make it unhappy, it will try to
make itself happy again.
His exact words were, "A system in equilibrium,
when subjected to a stress resulting from a change
in temperature, pressure, or concentration, and
causing the equilibrium to be upset, will adjust its
position of equilibrium to relieve the stress and
reestablish equilibrium."
