The efficiency of chemical reaction can be expressed as:
Correct answer: C. % yield
- A. Theoretical yield
- B. Actual yield
- C. % yield
- D. Maximum yield
Explanation
% yield is typically referred to as percentage yield. This is determined by dividing the number of moles of the product obtained by the number of moles of the 'limiting' reactant (the one present in the smallest amount), then multiplying by 100.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
