Chapter 12, Problem 7STP

Interpretation Introduction

Interpretation: To state whether statement I and statement II are true or false. To determine if statement II is the correct explanation of statement I.

Concept Introduction: Percent yield can be calculated by dividing the actual yield by the theoretical yield multiplied by 100.

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

Answer to Problem 7STP

Statement I is the correct explanation for Statement II.

Explanation of Solution

Percent yields involve the actual yield and theoretical yield. It can be calculated by dividing the actual yield by the theoretical yield multiplied by 100. Therefore, a percent yield must be greater than 0% and lesser than 100%.

Thus, the statement I is true.

The actual yield is the that is experiment value while the theoretical yield is the one that is calculated using the reaction information.

The actual yield is always more than the theoretical yield.

Thus, statement II is true.

Conclusion

Thus, the statement I is the correct explanation for Statement II.
