ALL my advanced A level theoretical chemistry revision study notes

GCSE Level introduction to basic thermochemistry and calculations

Use your mobile phone or ipad etc. in 'landscape' style

This is a BIG website, you need to take time to explore it [SEARCH BOX]

Part 0 for GCSE/IGCSE students (but a useful introduction for advanced level students including calorimetry)

Energetics - introduction to energy changes

(4 linked GCSE/IGCSE/O level pages listed below 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 for 9 investigations

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

2.1a-c Introducing enthalpies of ion hydration, solution, atomisation, lattice energy, electron affinity, solvation

2.1de Enthalpy cycles involving a salt dissolving

2.2ad The BornHaber Cycle calculations and uses, comparing theoretical and experimental lattice enthalpies

Part 3. Introducing entropy, feasibility of reactions, entropy and free energy calculations ΔG = ΔH- TΔS

3.1ag Introduction to Entropy :

3.2 Examples of entropy values and comments, entropy change for change of physical state

3.3a ΔS, entropy change and change of state

3.3b ΔS, Entropy changes and the feasibility of a chemical change

3.4ad Feasibility of chemical change, ΔG, free energy change equation, calculations and applications

3.5-3.6 Calculating equilibrium constants from ΔG equation, kinetic stability - thermodynamic feasibility
