A-Level Energetics: Thermochemical cycles using Enthalpy Change of Formation Worked eg and Practice

Worked example and practice questions using standard enthalpy changes of formation and Hess's Law to draw thermochemical cycles and calculate molar enthalpy changes for reactions.

The pdf could be given to students directly or used as a guideline for the teacher doing the worked example from the front of the class. It includes the answer with annotations and tips. The word document leaves space for the students to fill in the worked example themselves.

Extra practice questions are included at the bottom of the sheet.
