Short explanation
In the subtopic Percentage yield, this learning objective focuses on (chemistry only) Define yield as the amount of product obtained from a reaction. It sits within Yield and atom economy of chemical reactions (chemistry only) for AQA GCSE Chemistry 8462 Unit 4.3, so the explanation must stay anchored to quantitative chemistry rather than drifting into a general chemistry idea. Approved keywords to use include chemistry only. Percentage Yield. means the actual amount of product obtained compared with the maximum theoretical amount, expressed as a percentage Avoid the mistake of students often confuse yield with the theoretical yield, thinking it refers to the maximum possible amount of product rather than the actual amount obtained; instead, clarify that yield specifically refers to the actual amount of product obtained from a reaction, not the theoretical maximum For exam answers, clearly define yield as the amount of product obtained from a reaction in your answers
