Chapter 11, Problem 85A

Interpretation Introduction

Interpretation : Whether percent yield can be more than 100% or not needs to be explained.

Concept introduction : Percent yield is the measure of efficiency of the chemical reaction.

Answer to Problem 85A

No, percent yield cannot be more than 100%.

It was calculated according to the relation given below

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

Explanation of Solution

No, percent yield cannot be more than 100%.

It is calculated according to the relation given below

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

This is because actual yield cannot be greater than theoretical yield. So ratio of actual yield to theoretical yield is always equal or less than 1. The only possibility is if there is an impurity present in the compound but, generally it is always less than or equal to 100%.
