Revising Advanced A Level Chemistry

 Doc Brown's Chemistry Revision Notes


Part 0. Energetics - introduction to energy changes

(4 linked GCSE/IGCSE/O level pages including practical calorimetry methods)

Reversible reactions and energy changes

Activation energy and reaction profiles

Introduction to bond energy/enthalpy calculations

Calorimetry methods and energy transfer calculations from calorimeter results

Parts 1 to 3 are only for Advanced A Level Students

PLEASE note that delta H/S/G values vary slightly from source to source, so I apologise in advance for any inconsistencies that may have arisen as I've researched and developed each section.

Part 1. Basic thermochemistry, calorimetry and enthalpy changes

1.1 Advanced Introduction to enthalpy changes enthalpies of reaction, formation, combustion

1.2a-1.2b(iii) Thermochemistry Hess's Law calculations, enthalpies of reaction, combustion, formation etc.

1.2b(iv) Bond Enthalpy Calculations

1.3ab Experimental methods for determining enthalpy changes and treatment of results

1.4a-b Enthalpy data patterns - combustion of alkanes linear aliphatic alcohols, bond enthalpies and bond Length

1.4c-d Enthalpies of neutralisation, enthalpies of hydrogenation and evidence of aromatic ring structure in benzene

Extra Question page A set of practice enthalpy calculations with worked out answers

Part 2. Extension of defined enthalpies leading to a full exposition of Born-Haber cycle calculations and uses
