Percent Yield

The ______________ yield is the maximum amount of product possible in a reaction. This determines the amount of product that should be produced in a perfect setting

• Percent
• actual
• stoichiometry
• theoretical

Actual Yield

• The amount of product you make after a chemical reaction has occurred.

• The amount of product you expect to make after a reaction. This is a calculated value.
