Which of the following best describes what percent yield indicates in a chemical reaction?
A
The concentration of the product in the final solution.
B
The ratio of the actual amount of product obtained to the theoretical amount, expressed as a percentage.
C
The amount of product predicted by the balanced chemical equation.
D

Verified step by step guidance1
Understand that percent yield is a measure used to compare the efficiency of a chemical reaction in producing the desired product.
Recall that the theoretical yield is the maximum amount of product that can be formed from the given amounts of reactants, calculated using stoichiometry from the balanced chemical equation.
Recognize that the actual yield is the amount of product actually obtained from the experiment or reaction.
Percent yield is calculated by taking the ratio of the actual yield to the theoretical yield and then multiplying by 100 to express it as a percentage, using the formula: \(\text{Percent Yield} = \left( \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \right) \times 100\%\)
Therefore, percent yield indicates how close the actual amount of product obtained is to the maximum possible amount predicted by stoichiometry, reflecting the efficiency of the reaction.
