Enthalpy Changes A* Revision OCR A-Level Chemistry

Описание: Enthalpy Changes and Calorimetry OCR A-Level Chemistry Revision. Module 3: Periodic Table and Elements. I help students learn and understand the Enthalpy Changes topic, which is a difficult part of the OCR A-Level Chemistry specification. I cover the definition of enthalpy, the enthalpy changes definitions (enthalpy change of reaction, enthalpy change of formation, enthalpy change of combustion, enthalpy change of neutralisation), exothermic and endothermic reactions including Enthalpy profile diagrams, Average Bond Enthalpies and Calorimetry with Exam Questions to help students apply their knowledge in exam contexts.
