The theoretical yield of a reaction is
Correct answer: A. the maximum mass of product calculated from the balanced equation and the limiting reactant
- A. the maximum mass of product calculated from the balanced equation and the limiting reactant
- B. the mass of product actually obtained in the laboratory
- C. always equal to the mass of the limiting reactant
- D. the mass of the excess reactant left over
Explanation
Theoretical yield is a calculation, assuming the reaction goes to completion with no losses and no side reactions, and it is the standard against which real performance is judged. What is actually collected is the actual yield and is nearly always smaller. Comparing the two as a percentage tells a chemist how efficient the process was.

About Theoretical and Percentage Yield
Theoretical yield is the maximum product predicted from a balanced equation and the amount of limiting reactant. Work includes identifying the limiting reagent, comparing theoretical and actual yield, and calculating percentage yield using stoichiometric mole relationships.

More Theoretical and Percentage Yield questions
A reaction has a theoretical yield of 25 g but only 20 g of product is obtained. The percentage yield is
The actual yield of a reaction is usually less than the theoretical yield for all of the following reasons EXCEPT
How many grams of calcium oxide are produced when 1 mole of calcium carbonate decomposes completely, given CaCO3 gives CaO + CO2?
Consider the given balanced chemical equation: 2H2 + O2 gives 2H2O. If 4 g of H2 reacts with 32 g of O2 to produce 28 g of H2O, what is the percentage yield of the reaction? (Molar mass of H2 = 2 g/mol, O2 = 32 g/mol and H2O = 18 g/mol)
