Real World Stoichiometry (draft)

In the real world, reactions do not occur under perfect conditions - this only occurs in the theoretical world.

Limiting Reagents

When conducting most reactions, the amount of one reactant added is rarely in perfect proportion to the amount of another reactant added.

If the molar ratio is

By definition, the limiting reagent is the first reactant to be fully consumed, limiting the reaction from continuing to take place.
