Key Concepts

Percent Yield

Percent yield is a calculation that expresses the efficiency of a chemical reaction by comparing the actual yield to the theoretical yield. It is determined by dividing the obtained (actual) amount of product by the maximum possible (theoretical) amount predicted by stoichiometry and multiplying by 100 to get a percentage.

Limiting Reagent

The limiting reagent is the reactant that is consumed first during a chemical reaction, thus restricting the amount of product that can be formed. Identifying the limiting reagent is crucial for determining the theoretical yield since it controls the maximum reaction output.

Theoretical Yield

The theoretical yield is the maximum amount of product that could be formed from the complete conversion of the limiting reagent, according to the mole ratios from the balanced chemical equation. It provides a benchmark to compare against the actual yield obtained in an experiment.

Stoichiometry

Stoichiometry involves calculating the quantitative relationships between reactants and products in a chemical reaction based on a balanced chemical equation. This includes converting masses to moles (using molar masses), using mole ratios to relate reactants to products, and determining the theoretical yield of the reaction.
