Percent Yield: Percent Yield Limiting Reactant Worksheet

Percent yield, also known as reaction yield, is a measure of the efficiency of a chemical reaction. It is calculated as the ratio of the actual yield (the amount of product obtained) to the theoretical yield (the amount of product that would be obtained if the reaction went to completion) multiplied by 100.

Percent yield can be used to evaluate the effectiveness of a reaction, identify sources of error, and optimize reaction conditions.

Examples of Percent Yield Calculations

• If a reaction produces 10 grams of product and the theoretical yield is 15 grams, the percent yield is (10/15) x 100 = 66.67%.
• If a reaction produces 12 grams of product and the theoretical yield is 10 grams, the percent yield is (12/10) x 100 = 120%.

Limiting Reactant

The limiting reactant is the reactant that is completely consumed in a chemical reaction, thereby limiting the amount of product that can be formed. To identify the limiting reactant, we compare the mole ratios of the reactants to the stoichiometric coefficients in the balanced chemical equation.

The reactant with the smallest mole ratio is the limiting reactant.

Examples of How to Determine the Limiting Reactant, Percent yield limiting reactant worksheet

• Consider the reaction: 2A + 3B → C. If we have 2 moles of A and 4 moles of B, the mole ratios are:
  • A: 2 moles / 2 = 1
  • B: 4 moles / 3 = 1.33

  Since A has the smaller mole ratio, it is the limiting reactant.

• Consider the reaction: A + 2B → C. If we have 3 moles of A and 2 moles of B, the mole ratios are:
  • A: 3 moles / 1 = 3
  • B: 2 moles / 2 = 1

  Since B has the smaller mole ratio, it is the limiting reactant.
