Chapter U4.26, Problem 2E

Interpretation Introduction

Interpretation: The explanation regarding percent yield is to be stated.

Concept introduction: In a chemical reaction, the amount of product formed in the relation to the amount of reactant consumed is term as yield. Yield is generally expressed in percentage.

Answer to Problem 2E

The percent yield is expressed as shown below.

  $\text{Percent}\text{yield}=\frac{\text{Actual}\text{yield}}{\text{Theoretical}\text{yield}}\times 100$

Explanation of Solution

The amount of product formed by the calculation of balanced equation and stoichiometry of the reaction is termed as theoretical yield. The amount of product produced in a chemical reaction is termed as actual yield. The ratio of actual yield to the theoretical yield is called percentage yield of the reaction.

The expression of the percent yield is shown below.

  $\text{Percent}\text{yield}=\frac{\text{Actual}\text{yield}}{\text{Theoretical}\text{yield}}\times 100$

Conclusion

The percent yield is ratio of actual yield to the theoretical yield.

  $\text{Percent}\text{yield}=\frac{\text{Actual}\text{yield}}{\text{Theoretical}\text{yield}}\times 100$
