Question

Quizplus · Accepted Answer

The percent yield of a reaction compares the actual amount of product obtained to the theoretical maximum amount that could have been produced. An efficient chemical change should have a high percent yield, indicating that a large proportion of the reactants were converted to product. Therefore, the percent yield is a useful measure of efficiency.
