Key terms
Yield
The amount of product obtained from a reaction. In Percentage yield, this term helps explain (chemistry only) Define yield as the amount of product obtained from a reaction for AQA GCSE Chemistry 8462 Unit 4.3.
Percentage Yield
The actual amount of product obtained compared with the maximum theoretical amount, expressed as a percentage.
Percentage yield
The actual amount of product obtained from a reaction compared to the maximum theoretical amount, expressed as a percentage.
Theoretical yield
The maximum amount of product that could be formed from given amounts of reactants in a chemical reaction.
Percentage yield
The actual amount of product obtained from a reaction compared to the maximum theoretical amount, expressed as a percentage.
Actual yield
The measured amount of product obtained from a chemical reaction. In Percentage yield, this term helps explain (chemistry only) Calculate percentage yield from actual yield and theoretical yield for AQA GCSE Chemistry 8462 Unit 4.3.
Reversible reaction
A chemical reaction that can proceed in both forward and reverse directions, leading to a dynamic equilibrium.
Completion of reaction
The state in which all reactants have been converted to products, which may not occur in reversible reactions.
Percentage yield
The actual amount of product obtained from a reaction compared to the maximum theoretical amount, expressed as a percentage.
Product loss
The reduction in the amount of product obtained due to factors such as incomplete separation from the reaction mixture.
yield
The amount of product obtained from a reaction. In Percentage yield, this term helps explain (chemistry only) Explain why yield may be reduced if reactants take part in unexpected reactions for AQA GCSE Chemistry 8462 Unit 4.3.
unexpected reactions
reactions that occur which were not anticipated, potentially reducing the yield of the desired product.
Percentage yield
The actual amount of product obtained from a reaction compared to the maximum theoretical amount, expressed as a percentage.
Actual yield
The measured amount of product obtained from a chemical reaction. In Percentage yield, this term helps explain (chemistry only) Use ratios, fractions and percentages in yield calculations. (MS 1c) for AQA GCSE Chemistry 8462 Unit 4.3.
Percentage yield
