LIMITING REACTANT: RECAP

1.

You can recognize a limiting reactant problem because there is
MORE THAN ONE GIVEN AMOUNT.

2.

Convert ALL of the reactants to the SAME product.

3.

The lowest product answer is the correct answer, called the
THEORETICAL YIELD.

4.

The reactant that gave you the lowest answer is the LIMITING
REACTANT.

5.

The other reactant(s) are in EXCESS.

6.

If you have to find more than one product, be sure to start with the
limiting reactant. You don’t have to determine which is the LR over
and over again!

7.

To find the amount of excess, subtract the
amount used from the given amount.
