A COEFFICIENT is a number placed
IN FRONT of a molecule to “balance”
the # of atoms of REACTANT with
Na

ONE
WAY
REVERSIBLE
under the right conditions
(ammonia)
The reaction can “shift” left or right under certain conditions
EXCESS REACTANT shifts right (excess product, left)
REMOVING REACTANT shifts left (removing product, right)
ADDING/REMOVING ENERGY can shift it as well
