Energy Changes flashcards
Every deck we have for Energy Changes, part of AQA GCSE Chemistry. 94 questions written against the published specification, free to study with no account. Each deck schedules its own reviews, so cards you find hard come back sooner than ones you have already got right.
Exothermic and Endothermic Reactions
26 cardsWhich way energy is transferred in each type of reaction, everyday examples and uses, and the required practical measuring temperature change.
Reaction Profiles and Activation Energy
22 cardsDrawing and reading reaction profiles for both types of reaction, what activation energy means, and how a catalyst changes the picture.
Bond Energy Calculations
22 cardsWhy breaking bonds takes energy and making bonds releases it, and calculating the overall energy change of a reaction. Higher tier content.
Cells, Batteries and Fuel Cells
24 cardsHow chemical cells produce a voltage, the difference between rechargeable and non-rechargeable, and how a hydrogen fuel cell compares with a rechargeable battery. Chemistry only content.
