Chapter 11.4, Problem 31SSC

Interpretation Introduction

Interpretation:

The type of yield, theoretical yield, actual yield and percent yield needs to be identified which is a measure of the efficiency of a chemical reaction.

Concept introduction:

The actual yield of the product is the amount of product, which form at the end of reaction experimentally whereas theoretical yield represents the amount of product calculated by expecting that 100 % of reactant change to product. The percent yield can be shown as:

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

Answer to Problem 31SSC

Percent yield is a measure of the efficiency of a chemical reaction.

Explanation of Solution

Theoretical yield is the amount of product formed according to the balance chemical reaction from the given moles and mass of reactant molecules. Actual yield is usually little lesser than the theoretical yield due to unavoidable process errors. Thus, the accuracy and efficiency of a chemical reaction can be measured in terms percent yield of the reaction.

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

Conclusion

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