Limiting Reactant Sandwiches

It is the reactant that produces a lesser amount of product. (a)  

• Excess Reactant

• Percent Yield

• Limiting Reactant

• Co-Factor

In a chemical reaction, the reactant that determines the amount of product formed is called the:

• Excess Reactant

• Percent Yield

• Limiting Reactant

• Catalyst
