Limiting and Excess Reactants

How do you determine the limiting and excess reactants? Determining which reactant is the limiting or excess reactant is just a matter of figuring out which one will run out of first in a reaction. In a reaction, reactants are not always combined in proportions so that each one is completely used up. The limiting reactant determines the maximum amount of product that can be formed.
